RE: About Sigma: beware ??
I think it is not fair to gerealise based on the single known Canon compatibility problem. Sigma gives information about this on their web site, it affects a known range of cameras and Sigma offers a free upgrade for all lenses where this is technically feasible. Not bad for customer service. Otherwise it is a mixed picture for me. Of my two Sigma lenses the 2,8/28-70 is very sharp, it holds very well against the FA 24-90 but the AF is less consistent than that of the Pentax ... and the 12-24 is unique anyhow but not as sharp as I would like it to be. Both feel solid and seem to have good build quality, something that cannot be said about the FA 24-90. Sven Zitat von Amita Guha [EMAIL PROTECTED]: Unfortunately and very frustratingly I have great problems with the new Sigma 18-125 DC f3.5-5.6 for Canon (20D). Nate and I both have this lens and Nate uses his on the 20D without a problem. (That's the only lens I could afford when I finally got enough money to buy the digital stuff.) Optically - for a zoom of this type - it's not bad at all. However it is consistently inconsistently malfocusing. Typically it will focus at a point closer than the aimed focus point. Nate has had this problem on several of his lenses. He says that Sigma's lenses have trouble communicating with Canon bodies. He says you need to get it replaced, which you're already doing. But give the lens a chance when you get a new one - it's really good for the kind of lens it is. What do you guys think - can I trust a Sigma EX 70-200 f.2.8 APO HSM DG will do a good job, or will it let me down like the 18-125? It just depends on the lens; sometimes you get a stinker, but it's never happened to me. I have a couple of EX lenses, the 15mm fisheye and the 20mm f/1.8, which I like a lot. Amita

Re: ME-F
Oh, that explains it then - you haven't tried the AF lens yet... It is so ridiculously slow (and heavy) that I find it hard to understand how this ever made it into customers hands. Honestly, after you push the button you can watch the lens slowly approaching focus ... still focussing ... yes, almost, ... just a bit more ... o.k., done it ... focus achieved. I think the reason for the commercial failure simply is that it did not work well enough. Sven Zitat von Joaquim Carvalho [EMAIL PROTECTED]: Brian Walters wrote: I suspect that the commercial failure of the ME-F with its autofocus lens is what set Pentax back in the autofocus race. After the ME-F they went back to manual focus systems in the P series and were not ready to meet the challenge of the Minolta 7000. Can't understand why, as a focus assist system it works really well. With low ligh it's a bit worse than the DS but not too much. Was it too expensive? When I receive the autofocus lens I'll report on how it works.

AW: Rumors About Pentax's Future
So am I. The 8 Megapixel model of the other brand is now much cheaper than what I paid for the ist D 1 1/2 years ago. I do not regret that I paid this money but I want a comparable body from my brand soon! And if there is no clear indication that there will be one in the forseeable future then I don't know how to convince myself to stay with Pentax. Lenses, for sure aren't a plus for Pentax either, these days. It took me quite a while to get hold of a FA 2,0/35 (no longer available new) and a FA 2,0/24 seems to be equally rare. I have meanwhile bought my second Sigma lens and I really didn't want to do that... We all want to believe that there is a future for Pentax but what is it that we base this upon? The roadmap? I can make this up in 1/2 an hour. The 645 D mockups? ... The other brand has three different shift tilt lenses to choose from!

AW: istd or istds or wait?
Maybe ... wait. I have the ist D since it came out and it has become my main camera - but I don't use it exclusively. With all the advantages it has, the ease of use, the clean 'digital' images, the good low light capabilities, if you have the time and a good film (and the light) then 6 MPix is not better that 35mm film and certainly no match for medium format. Both ist D and Ds are very good 6 Megapixel cameras - but 6 MPix is not the end of the story if you ask for fine detail. Is there a Pentax DSLR with 8 MPix or rather 10 MPix around the corner?

Re: Pentax 645
I think it is difficult to tell from a picture what exactly caused the vibration. So exact proof will be hard to get. Reichmann SAYS that the obvious blur that he shows in his pictures comes from shutter induced vibration - but how does he know? It could have been wind, nearby machinery or he himself. An impact of the first shutter curtain seems hard to believe. If I hand-hold my 6x7, set it to B, pre-fire the mirror and release the shutter I can hardly hear the first curtain being released - and I can not feel it. From my perception, this impact would not cause a Auto 110 to tremble. Sven Zitat von Mark Roberts [EMAIL PROTECTED]: William Robb [EMAIL PROTECTED] wrote: From: [EMAIL PROTECTED] I'm a regular reader and occassional contributor to both forums. The shutter bounce vibration nonsense has been debunked numerous times. Read Wheatfield's earlier post.

I've proven that conclusively in terms of my own work. I think it's time this mysth got debunked once and for all. Tomorrow after work, I'll set up a test and video the damned thing. I don't really see what debunking needs to be done - no one has ever claimed that the shutter vibration is a problem at all times, under all conditions, only that the massive shutter of the 67 can cause problems at certain shutter speeds with long lenses *if certain precautions aren't taken* (sufficient tripod and head - which some people new to the 67 system underestimate). Reichmann's site shows the issue clearly and then specifically shows how it can be totally eliminated with the correct set-up.

RE: DA 14 vs. Sigma 12-24
I also have no doubt that the DA is the 'better' lens. Inspecting 100% crops on computer screens however isn't really what lenses are made for. I do not say that this makes no sense, but it should be put into context. If stopped down to 8 or 11 the Sigma is good enough to produce 15x20 prints of very acceptable quality (to me).

I did this in part to clarify in my own mind what is going on when people complain about the DA 14 being weak in the corners. I know, I know -- I am comparing a prime to a zoom. No contest, right? Well, the Sigma is the only lens I have access to that includes the 14 mm. focal length. Also, the last time I compared a prime to a zoom, it was the DA 14 vs. the DA 16-45 at 16 mm. -- and the zoom won. The subject was, as usual, an adobe (mud brick) wall, with the camera at about one meter distant. I used ISO 200, and a tripod. All comparisons were at actual pixels, although I went to 200% in one case. Firstly, the DA 14 becomes progressively sharper through f8 (the smallest aperture I tested). The center is noticeably better at f4. At f5.6 the corners sharpen up considerably, then improve a bit more at f8. Stop this lens down. Now the comparison. Both lenses wide open: (f2.8 for the DA 14, f4.5 for the Sigma). The DA 14 is much sharper in the center. It is mostly sharper also at the edges and in the corners, although the difference is less. The Sigma may be slightly better at the left edge and in the lower left corner. Where the Sigma seems better, it is not by much. Where the Pentax is better, the difference is very clear. F5.6 (both lenses): The Pentax is far better in the center, slightly better at the edges and in the corners. F8 (both lenses): The DA 14 is much better in the center and corners. It is also better at most edges, the exception being the left edge where the Sigma seems a bit sharper. The DA 14 is clearly the better lens overall. What is interesting is that it has an arc of slight weakness from the lower left corner to the left edge (about 225 to 275 degrees). Shouldn't lens performance be symmetrical? I would think that even assymetrical lenses should be symmetrically assymetrical. Any thoughts? BTW, on aperture priority the Sigma consistently exposed the images 1 EV less than the DA 14. The Sigma seemed to be underexposing. Joe - Ende der weitergeleiteten Nachricht -

Jens, as you already have a 45 CT 5 flash doing TTL you should be alright using the adapters you have on the 60 CT 2. Both flashes are from the same period, when Metz first tried TTL flashes with the SCA 500 system. This was before the SCA 300 System became popular. AFAIK the two systems are backwards compatible so that on a 45 CT 5 or 60 CT 2 you can either use the older C8x adapters or the later SCA3xx adapters together with a SCA 500 C cable. You can not however use a SCA300 flash with an old C8x adapter. Regards, Sven -Ursprüngliche Nachricht- Von: Jens Bladt [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 9.

If you inspect your camera with the lens talken off you can see some of it. However, using a 1.4 lens with manual focus on a ist D screen without focussing aids is a worst case scenario. If you really want to rule out focussing errors on your side you need to use a magnifier or refconverter in the 2X position. I need some help understanding how this helps. The ist D finder image is small if compared to film SLRs, especially those meant for manual focus. Also, the finder screen does not have focussing aids such as microprisms or a split image field. This means that the error margin that you have when focussing manually is relatively high. This is not a problem when the lens is stopped down a little and/or if the resulting prints are viewed under normal viewing distance. However, if you use a fast lens (like a 1.4) wide open AND want to inspect 100% crops of the resulting image on a computer screen it is well possible that your focussing was not accurate enough for this extreme setup, i.e. it did not fall within the shallow DOF range of the lens. About the only thing you can do to improve accuracy here is to focus with the help of a magnifier or a refconverter attachment using its 2x magnifying position. This certainly is nothing that you would want to use for normal photography work. All it would tell you is wether the camera screen is out of alignment (in which case it would have to be adjusted by Pentax) or if the error is more on your side. Regards, Sven

Re: HELP! *istD problems
As has been said before, there are two separate optical systems 1) lens to focussing screen and 2) screen to eye - so that the diopter adjustment does nothing to the focus of the image on the screen. Adjust it so that you can see the screen best and forget it. The AF does NOT 'see' the same thing as the screen. When the position of the AF module (that sits under the mirror) relative to the lens is different to the position of the screen, both result in a different focussing position of the lens.

For the longest time, I've been having problems with my pics being quite soft wide open. I thought that it was just because the lens was wide open. I have alot of manual focus lenses, which I use often. The problem showed up mainly with them, so I went back to look at some of the pics more carefully, and I noticed a pretty consistent pattern. There were areas of sharpness alright, but not where I wanted them to be. I was consistently back-focusing. So I did some tests. I mounted my FA* 85 1.4 on the camera, set it on a tripod, and proceded to make some careful experiments to see if I could put the blame where it belonged, on me or the camera. The setup was your typical measurebating focus test setup. I had a ruler at an angle with a target off to the side of it where I focused. I took pictures with and without autofocus. The result: no matter how carefully I manually focused, the autofocus was always right on the money, and I always back focused. I adjusted the diopter after autofocusing to see if I could match the camera's focus point, took my glasses off, put my glasses on, danced around the camera, but no matter, I always back-focused. What is going on here? Doesnt the autofocus see the same thing I do? Or is something mal-adjusted somewhere? When I look through the viewfinder after I auto focus, it seems to be in decent focus, but it looks pretty much the same as when I focus manually. If I then switch to manual focus and get it out of focus and back in and take the pic, it is back-focused! Am I going blind?
AW: Manual Focus Pentax Glass on istD
I happily use all my manual lenses and I think that the differences discussed between lenses and betwen digital and analog applications are overrated - and the words on the digitally improved labels that some lenses now carry are mostly marketing blurb. What can be said is that comparing lens performance has become much EASIER with digital, so that many people do it - but you can still make many mistakes that spoil the results and lead you to false conclusions. I have myself 'compared' many of my lenses and I have however fooled myself many times... As an example, when you look at 100% crops of images taken wide open, you are not only judging the lens - you are also judging the focussing ... unless you made sure that the focussing was VERY accurate (i.e. done manually with a loupe). Autofocus is not good enough here. My bottom line is that with digital it is LESS important which lens you take. At least stopped down a little they all work well. As an example, here is a comparison between a lens with a mediocre reputation, the M 2,8/40 and the F 1.4/50 of which some say it is the best, both at f=8. www.mynetcologne.de/~nc-kellersv2/4050.jpg Yes, you can see the difference - but it isn't big.

Re: Question on MZ-S quirk
Mine does exactly the same and I also regret that it does. Setting the AF button up for AF + AE-L would give this button at least some meaning. Regards, Sven Zitat von Joe Wilensky [EMAIL PROTECTED]: I grabbed a like new MZ-S from KEH last month (it truly was like new, and only four rolls had gone through it based on the data imprinting count -- I don't think it was reset, either, because it looked like it had never been used at all). I had borrowed an MZ-S from a list member briefly a little over a year ago, and had been thinking about the MZ-S ever since ... anyway, the question is whether this is a quirk -- I changed the Pentax Function 6 to make AF and AE both lock with a press of the AF button on the back. I didn't realize it at the time, but this completely disables the AE-L button on the back so that it has essentially no function at all. (It will still wake up the camera to give a meter reading, and it still will select Pentax Functions in the PF mode, but it will no longer lock exposure.) This is true for the AE-L button on the grip, too. I couldn't remember if I had tried the AE-L button before this, and I was truly bewildered until I thought to switch the PF back so that only AF is performed by the AF button on the back. Lo and behold, the AE-L button works fine again. The manual, of course, makes no mention of this. Is it a quirk anyone else has noticed? Joe

Yes, exactly, in automatic mode both speeds and apertures (with an A lens) are 'stepless', i.e. the program might decide to use f=6,27 @ 1/362s. But otherwise your question is a good one. As there is no exposure compensation dial and the ISO speed is set automatically, the only remaining option would be to modify the pattern on the film canister to show a higher film speed to the camera Does that work? I had thought of doing that when I wanted to push the film but wasn't sure if I might fry some thing. The DX coding is no secret and I am sure it can be found on the web. To modify it you would either have to grind off or add paint (or a piece of tape) where needed. Regards, Sven
RE: slide exposure?
Francis, I think your camera meters and exposes stepless - it only indicates the speeds rounded to the next full value. But otherwise your question is a good one. As there is no exposure compensation dial and the ISO speed is set automatically, the only remaining option would be to modify the pattern on the film canister to show a higher film speed to the camera - but that is not an everyday solution. Anyhow - are you sure you WANT to expose 1/2 stop under? My advice would be to invest in a test roll of the film you want to use and try it out. Be sure to use the exposure lock often, i.e. whenever there are abnormal lighting conditions and try to 'balance' the lighter and darker portions that the camera sees before locking (at least that is how I do it) ... and I am sure you will get good results. Ultimately, when you start bothering about 1/2 stops you will need a different camera ;-) Regards, Sven -Ursprungliche Nachricht- Von: Francis [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 15.

RE: Have you ever heard of Porst lenses?
Porst is not my primary brand of interest but I still think that what has been said do far does not do this name justice. Porst certainly is one of the great names in the German photo industry since the twenties, although he - to my knowledge - never actually made cameras. However, he had many, many cameras made to his specs before WWII (not just rebadged) and has played his part as the largest (by far) retailer (mainly mail order) before and after the war. Porst is and always was a 'West-German' company. They imported Japanese as well as east German (GDR) cameras. Since the late eighties Porst is no longer family owned and the brand has since then changed ownership several times. Sven Zitat von Jens Bladt [EMAIL PROTECTED]: Many brand names have been reused as names for products that have nothing to do with the original brand/manufacturer. Trading companiers, that have no production anymore or have no real realations with the original brand buy old names. Exakta, Contax, Voigtländer - are examples - to mention a few. I believe ther's a market for just names. When a manufacturer closes down, they can make a profit by selling or licensing their name/brand. A Cosina named Porst is still not a Porst, just a Cosina with borrowed name tag. BTW, I may be confusing Alpha (made by Zeiss) with Acra Swiss, a large format Swiss camera - portable large format, great for landscapes etc. I was reviewed in Outdoor Photographer a couple of years back.

Kostas, probably a 6-element Cosina lens as it was offered by Porst together with Cosina made cameras. I have found only one other reference to a 1.2/55 lens and that points towards Vivitar - but Vivitar never made lenses themselves.

Hello Jim, welcome to this list (if I may say so, as I currently contribute hardly anything). I remember your name from the medium format other brand camera list and I keep a bookmark for your site to show other people how nice landscape photograpy can be and how beautiful your country is. As for the *ist D and the Ds ... I have the *ist D and I am very happy with it. I have also tried the Ds. The differences between both are marginal if you look at how easily both can be operated, all in all. Using M or K lenses is easy on both - I use them a lot. I use only one M42 lens on the D, a 50 mm Macro Takumar which works fine as well. Something that took me a while to realise: If you have time ... you don't need ANY metering with a digital (SLR). Just select exposure according to your best guess and give it a try, check and correct if necessary. One last thing that has not been mentioned I think, is that there is no vertical grip for the Ds (and will not be, as there are no contacts). I always have the grip mounted to the D as it really improves the handling. Also, the D has no picture modes... Best Regards, Sven Keller Zitat von Jim Hemenway [EMAIL PROTECTED]: Hi Folks: I'm new to this list. Along with some other brand cameras, I've been shooting with a Pentax ZX-5n. Since I have a bunch of AF lenses for it, I'm thinking of getting the *isD for digital work.

If screw mount lenses are used on the D, is metering available? When I handled a D at a camera store several months ago I was told that there wasn't any metering possible for those lenses... but then I later heard that some sort of software upgrade had been made available. Is this true? Also, can anyone here tell me if one can use screw mounts on the DS? Other than the price difference, is there a reason to get the DS?

Alex, you can rub as long as you want with a piece of cotton towel. The ME Super mirror coating is quite sturdy, unlike the silver coating on really old cameras. Even if you scratched the mirror it would not matter - you would not see a difference in the viewfinder.

Re: Use of Green Button (was Re: istDs - what a great camera!)
If I remember correctly, operating the DOF preview lever around the shutter release does the same than the green button in manual on the *ist D (I usually use the green button however). So as the *ist Ds HAS DOF preview this COULD work similarly. If this worked like on the *ist D, the cheaper model could be the better choice alltogether.

Shel From: Paul Stenquist [EMAIL PROTECTED] No, it isn't necessary to press the green button for a subsequent shots at the same exposure. From: Anders Hultman [EMAIL PROTECTED] No. A press on the green button does a light metering that takes the aperture setting on the lens into account, and sets the camera to a suitable shutter time. That shutter time remains set until you a) press the green button again or b) change the shutter time manually with the Tv wheel.

I think that's a good thing - there has to be a way to check the effect of the current settings without altering any of them.

Re: viewfinder magnification
I don't quite buy that. What determines the size of the viewfinder image is the size of the frame the screen sits in (as long as we are talking +/- a millimeter). Make that frame a little bit larger and you have a 100% viewfinder. Of course, all elements that attach to the mirror box have to be 'accurate' but I don't see why that would be so difficult here. Even with a 90% viewfinder I would have hoped that what I see is from the center portion of the image, not from an edge... I have always argued the *practicality* of any 100% viewfinder. A 95% finder already shows *almost all* of the image: 95% of 24x36 is 23.4x35.1 mm (for APS-C it is 23.5x15.7 vs. 22.9x15.3). No matter what application you are thinking of for either a negative or a slide, you will have a hard time actually *using* more than 95% of it. A slide frame will cut away about 7% and any lab (including home printing) will probably cut away more. In that sense it is *correct* to show 95% as it gives you a better indication of what you will eventually get than 100%. Sven Zitat von [EMAIL PROTECTED]: I believe the manufacturing tolerance of a 100% viewfinder is way too difficult and expensive. It is not difficult to understand why once you have seen how the viewfinder is assemlbed. Every piece has to be 100% accurate (mirror, screen, pentaprism, eyepiece). Besides, even if the factory could do it at reasonable cost, the regional service centres can't. Alan Chan http://www.pbase.com/wlachan This is probably a silly question which has been discussed to bits, but I was wondering if someone could give me the quick answer as to why it was too hard to put a 100% viewfinder in the ist D (as opposed to the 90something percent..) I think it might be too expensive. It might have other tradeoffs in things like viewfinder image size. It's not impossible--most if not all of Nikon's F-series pro cameras have 100% viewfinder coverage and I believe at least one of their new pro digital cameras has 100% viewfinder coverage. Shouldn't it even be easier given that the image area isn't as big as the image area of film? OTOH, most Nikons have HUGE pentaprisms. That's not very Pentax-like. DJE

Re: 14mm DAs on eBay (was RE: Last rant, for a while, maybe)
Also (and I think that's too in Ebay's rules) the feedback should take into account how *both* partners handle possible complaints. If I (as a seller) provide feedback immediately after I ship the goods I cannot do this. If a buyer has a problem with what he received from me I certainly do my best to satisfy him - but I also expect him to be reasonable. This is still part of the transaction and included in my feedback. Leaving the feedback of both partners disclosed for some weeks (and whether or not they have given any) would work well, I guess, but it would probaby lead to more negative feedback in total - and I doubt that Ebay has any interest in seeing that. Sven Zitat von Gonz [EMAIL PROTECTED]: The hidden feedback is a good idea. Sellers also have the problem, not just buyers. If they give honest bad feedback to a buyer who was slow to pay, or gave the seller a hard time, then the buyer might get revenge by posting bad feedback in return, even if the seller completed his end of the bargain perfectly. Sellers with 100% pos feedback are especially vunerable to intimidation by unscrupulous buyers. rg Dan wrote: Yes this is a problem. I am in this situation myself as a buyer of sub-standard goods.

I'm in pretty deep with Pentax 35mm equipment. First, I do have a question about the 645N vs 645 NII. Does the N have the program shift like the NII? And does the NII program shift work like the MZ-S program shift favoring speed vs aperture? I can't really tell from the manual I downloaded I've always wanted a Rollei MF camera. Saw a 6003 w/ 80mm f2.8 on ebay and at a decent price, so I bought it. (it's got metering and almost all features of 6008 but without the full film magazine and w/o dark slide, but I can live with that). I knew going into it, new lenses are not cheap, but had seen reasonable prices on a few used. But did not realize the availablity of reasonably priced used ones are slim to none. (I would even settle for either using old lenses w/ stop down metering OR even renting them occasionally). I'm getting antsy waiting for lenses to come around at a fair price. My SECOND question is to anyone that has used BOTH Pentax 645N II system and Rollei 600x series. Should I dump the Rollei and get on w/ life and easy to find lenses at reasonable prices? Or should I wait it out to get the lenses I want (sees like it could be a long time)? I'm sure Pentax 645 lenses are good, but are Zeiss and Schneider lenses that much better to justify waiting? ( I can only image what the response to this will be on the Rollei list) Lastly, I greatful I can ponder such questions in my life, I know others are not so fortunate. John

AW: LX vs K2dmd vs Super Program
I always thought that Pentax missed the boat somehow with the Super A/Super program although it was a very successfull camera. When it came out I was a devoted MX user - and I immediately liked the LCD display in the Super A finder ... until I discovered that it did not provide the information it promised: no aperture readout in aperture priority or in Manual - combined with a DOF lever that *only* works correctly in aperture priority / manual. I always thought when setting out to design a new lens line they should have gone he whole way and invent something that provides all the information - always. It is still a nice camera, though.

I tried to scan the manual page in but my copy is so bad the scan was worthless. Yes the tools are to get the top cover, and eyepiece off. They made this a bit more involved on the K then they did on the M series but just note carefully the position of things and lay them out in order and you should have no problems. Most important tools are a GOOD set of jewelers screwdrivers, Phillips and Straight tip. There is also a small nut under the rewind knob, a pair of snap ring pliers, carefully used, will remove it. You may have to file the tips a bit to get a good fit, I use spanner wrenches but the SR pliers work fine. A good supply of cotton swabs (Q-Tips) is handy too. Most important tip is: Be patient, careful and DON'T FORCE ANYTHING. Most of the K's come apart rather easily but some are a little stubborn. Work over a nice fluffy white towel, dropped parts will be easier to see and won't bounce so far! If you get a replacement eyepiece before you disassemble it will be easier to see what needs done inside. If you get in trouble email me and I'll try to help. I have a couple of KX's here to look at.

Re: OTF metering question
I think that is a very good question (and I don't have an answer). 'Featurewise', OTF metering would have suited any later camera well. One reason they abandoned this technlogy (and this is just a wild guess) might have been the cost of the shutter with its titanium curtains. On these curtains you can print the dot pattern, that is obviously necessary. The later (vertically travelling) shutters where curtains do not 'roll up', might not allow to do this. Sven Zitat von Steve Jolly [EMAIL PROTECTED]: On Thu, 8 Jul 2004, Rob Studdert wrote: Technical limitations were few (at the time), the system had a ridiculously wide latitude with spectacular sensitivity however as it implemented via single SPD mounted at the base of the mirror cavity it could only offer CW metering. The style of implementation also meant that the only option for exposure offset in auto was by the exp comp dial around the ISO switch which has limitation when working with very slow or fast films. I suppose now it looks pretty feature poor these days, it still works remarkably well though. But why does only the LX support the feature, even though every modern Pentax body has the necessary sensor already (for TTL flash metering)? S
Re: 43 Limited Pre-computer?
Pål, I have mixed feelings about stories like the one you told below, about the old lens designer who towards the end of his life sets out to design the ultimate lens like in the old days... I can say, that in the industry I work in, similar stories are often used to motivate and entertain dealers and customers as they pretend to give them a look behind the curtain - but they are made up by marketing agencies for exactly that purpose and have very limited (if any) facts behind. If Mr. H. really is the chief lens designer then he most probably has not much to do with actual lens design but is spending his day reviewing Powerpoint presentations on business strategies... I don't know how close you are (or have been) to Pentax so I could be completely wrong and your story is entirely true... it just rang a bell. Sven Zitat von Pål Jensen [EMAIL PROTECTED]: Tom wrote: So how images from a particular lens can have a pre-computer look versus an 'absence of computer look' is simply beyond me. An how that can be blanketly stated, considering all the variables that will go into producing an image, is even more beyond me. Computers are used in order to eliminate various aberations in optical design among other things. Unfortunately, aberrations are giving lenses certain desireable (for some that is) characteristics. Some of these characteristics are related to bokeh (thats why some of the best corrected lenses, macro lenses, often show nasty bokeh characteristics). In the good old days the look produced from various lenses were very much in the hands of the lens designer (not the computer), in many ways a kind of art. With the 43 Limited Mr. Harakara (Pentax chief lens designer; the one who design all(?) the classic * lenses) and a famous japanese photographer (who's name I've forgotten but he was 77 years old when the 77 Limited was presented as a gift to him), set out to try to reproduce the pleasant image quality characteristics produced by pre-computer designed lenses (the good ones I assume); particularly the three dimensional feel of the images. In order to achieve this, they turned off the computer. Fine tuned various aberations and judged the results from the images themselves produced by the lens; not curves produced by test equipment. Hence the 43 Limited, and also the 77 Limited (to some extent at least), are designed very differently from normal lenses. Incidentally, the 31 Limited is not designed by Harakawa and is per! haps a more traditional lens. Pål - Ende der weitergeleiteten Nachricht -

Re: *istD firmware wishlist (open letter?)
I fear manufacturers development departments are not good at thinking 'outside of the box' and the short product cycles have cut down available time to let foreigners test prototypes - to make the developers aware of things they just did not 'see'. If we leave behind the 'film based' thinking, then ISO, aperture and shutter speed have a comparable influence on the final image and all three values should be equally easy to adjust and be equally displayed. What was a combination of two values now is a ISO-speed-aperture triangle (well, it always was...). If it gets darker I can adjust ISO to get the best noise/shutter speed/aperture compromise, if I need shallow DOF I decrease ISO so that I can shoot wide open, if I need a very high shutter speed I can increase ISO until I get 1/6000 and so on. I don't think it is an adequate solution having to turn two dials to adjust ISO and then afterwards not even being able to see what was set (without hitting another button). Sven Zitat von [EMAIL PROTECTED]: Neither my Nikon D100 nor my Nikon D1H display ISO in any of the normal displays. It'd be real tempting to say manufacturers didn't anticipate the desire to see the freely-changeable ISO number in the normal displays of a digital camera, except that my Nikon F5 DOES show ISO in the rear display. Still, perhaps the amateurs use DX coding mentality is to blame. Does the *istD have an auto ISO feature? Some of the other low and/or mid-level DSLRs do, presumably because film speed confuse tyros. OTOH, I rarely shoot more than a couple of frames at an inappropriate ISO before my brain tells me that the settings are fishy and I check to see where the camera is set. I'd expect most of you have good enough eye-meters that you aren't going to shoot at 1600 ISO by accident for long. DJE
FA 4/28-70 - something for the technically minded
I just found something interesting (at least for me) when trying to fix a FA 4/28-70 lens that wouldn't autofocus properly. On focal lengths longer than 50 it would not stop at precise focus but run past it and back the full travel, then stop, blinking 'unable to focus' in the finder. It did that on several Pentax AF bodies, so definitely the lens was at fault, not the body. On shorter focal lengths, everything was fine. Using the *ist D I found that the reported focal length was completely wrong for 50 and above (e.g. 31mm was reported for actual 70mm), so I took the lens apart and cleaned those contacts on the barrel that report the position of the zoom ring. Now both the transmission of the focal length and the AF work well again. So apparently, the the AF system takes into account the focal length, when calculating how much it has to displace the lens (or parts of it) to achieve focus. Somewhere in the lens the displacement/distance curve for each focal length must be stored, so when the AF system determines that the focus needs to be corrected from say 10m to 5m, the lens reports back as I am set to 50mm, you need to turn the AF shaft x turns... ...or something to that effect.

But that's because they communicate this information via the digital readout pin, not via the mechanical aperture coupler. As far as I know Pentax have never made a camera that used the maximum-aperture value (read from the A-mount contacts) and the aperture-delta value (from the aperture coupler) to calculate the actual lens aperture setting. ...

Re: On Sharpness (Confusion)
Boris, some remarks to add to your confusion ;-) o It seems that lenses from Canon/Nikon and the likes are often closer to what test procedures ask from a lens (contrast/sharpness), so Pentax lenses often get less good results - at least it looks like that in my part of the world and yes, it could well be that this is only so because Pentax advertises less in the magazines that publish the tests. We don't know what Pentax is thinking. If they really have a different take on what a good lens is, a more holistic approach instead of a 'scientific' one, based on measured sharpness and contrast, then they are certainly not good at 'selling' it. o We cannot be sceptical enough regarding our own perceptions and test procedures. I believe it is plain impossible to say anything about a lens based on a set of 4x6 prints. Even if you look at slides you need to always be aware that the loupe or the projector lens also is part of what you see. If you try to compare pictures taken of identical subjects you still have a whole bunch of issues that may make the results worthless. You just don't know whether somebody claiming a lens to be 'less sharp' in reality is talking about his shaky tripod... A person may also just not telling the truth - half of what is written on the internet is wrong. o We don't know if and how much sample variation there is. I personally have not been able to show much of this when comparing lenses of the same series but a) I do not have a testing laboratory and b) it is certainly possible the the particular lens that the owner claims to be less good is a lens that deviates fom the rest. I personally have concluded to stop 'testing' more or less. I have my personal lens favourites (my M 4/20, my FA 24-90, my M 2/35 my 3,5/35-105 stopped down) and I would go as far as recommending to give any of these a try, but no further. Sven Zitat von Boris Liberman [EMAIL PROTECTED]: Hi! It would appear from the most recent talk that Sharpness is more or less __the__ most important characteristic of the lens. However, from previous talks it has become my understanding that Pentax do not optimize their lenses specially for sharpness (except may be macro lenses and such). Pentax, AFAIU, optimize their lenses for plasticity, or overall smoothness of the picture. OTOH, Nikon are known for having their lenses tack sharp all over the frame. At least this is what I have accumulated in my small knowledge bag so far. Please unconfuse me - why all this talk about sharpness? I do realize that for digital lenses should be very sharp. Or at least, it would be a reasonable thing - to want one's lenses to be sharp. But sharpness is not all, right? Most recently I've sold my Soligor C/D 70-222/3.5 lens in favor of my Pentax SMC F 70-210/4.0-5.6. It could very well be that Soligor is sharper on some apertures. It is faster too. However it has rather ugly bokeh - at least to my taste, and general zoomish taste on the pictures I've been able to take with it. Pentax lens however is very smooth, very 3D, very pleasant. It is also lighter, has AF and is of course fully compatible with my MZ-6's electronics. It also allows for use of built-in flash at least for some of the focal distances. But this is already tech-talk. Still, why to be so aware of sharpness? I mean, if one wants sharpness, perhaps one should look for 3rd party lenses specially optimized for sharpness. Please unconfuse me. Thanks. Boris

In that sense EVERYTHING that offers a hands-on experience rather than a virtual one is positive. So if it is possible to explain a subject *without* using a computer I would always vote for that. The children *I* know will transfer and use the knowledge they have gained to computers anyway. Also, there is the thing with *understanding* a subject rather than knowing how to use a tool. With some effort in teaching optics and chemics you can come close to give a 14 year old a good understanding of *why* there is an image developing on that paper in that soup... I doubt the same level of understanding is possible with a computer or a bubble jet printer. They may be very skilled in using these and still don't have a clue... Sven ...

Re: Future Practicality of Film
I'll try to avoid the general opinion and will limit this to my personal experience... I do not photograph for a living - but I do take photographs almost every day. Over the years I have acquired some ;-) cameras with a variety of film formats (including a Minox and a Plaubel 4x5). I use many of them - not at random, but I often pick a different camera for the next film, sometimes even knowing that it might give 'inferior' results. Anyway, I just like it that way. What I have found since I bought the *ist D (my second digital camera) last October, is that I hardly use *medium format* any more. I didn't expect that (even though I sold a 40mm Distagon to fund the *ist D...) but my 35mm usage has not changed that much - I still do slides and happily continue to put negative film into a Spotmatic or a Rollei 35 or whatever, every now and then. As for less (almost no) medium format film use, I dont really know why this is so. One idea is that it is so *easy* to produce good quality prints with digital. True, you can match that quality with 35mm film, but everything needs to be right : The right film, the right lens, the right framing the right exposure, the right lab... I had always found it *easier* to produce a really good 12x18'' print from medium format as it has more reserves, but now digital has made this even simpler. Sven Zitat von Tom C [EMAIL PROTECTED]: I realize this list has a number of clairvoyants and unlicensed psychologists (hahaa), but I'm still interested in a general opinion. I have planned to buy a 67II for a number of years. I am now trying to determine the practicality of that course. What if in five years most photography is being done digitally as opposed to film? What if it's impractical for amateurs, even pros, to use MF/LF photography for any but the most eliteist of applications? Even considering the potential quality of MF over 135, it seems history may tell us that potential quality is not the sole factor in longevity and success. Both 620 and 828 saw their demise, even though they were a larger format than 135. If major players (camera and film manufacturers) are/were to move away from 135 film, how long is it until they move away from larger film formats which currently represent a smaller portion of the market than 135? For a fraction of the price of the price of a decent/complete MF system, there are other things... hot tub, SCT telescope for astrophotography... a surgery my wife has always wanted... I'm curious, what people think... is it possibly throwing money down the drain to 'invest' in additional film equipment? I'm not making a case for this, just wondering.

The feature I like best (apart from the exposure lock) is that an orange filter is put over the aperture readout window if an exposure correction is set, to remind you. Simply brilliant! I am always amazed what beautiful solutions Pentax engineers have come up with for certain functions ... only to forget about them for the next camera. There is a whole array of such things, like the one mentioned above. After the K2 DMD had this reminder, the ME did not have anything like that and would let you carry on shooting with 'corrected' exposure until the end of the film.

At ISO settings below 400 the camera will under-expose, at setting above 400 it will over-expose.(*) This problem can probably not be solved by a firmware update as there is no upgradeble TTL-software but some kind of hardware solution.

AW: The best 28-70 f2.8 zoom?
May I question why you are looking for a zoom anyway? I can't believe that whatever zoom is there is *very good* at f 2.8 so other than in an emergency you probaby will not use it at 2.8. The AF doesn't need the extra stop either - other than in an emergency... But if you *are* in an emergency, in really low light and still want to continue shooting (or, in brighter light, *really* need that extra shallow DOF), then you would be even better off with TWO stops extra, on top of the 2.8, that you can get from a 1.4/50 (if you don't have one already).

So, I was wondering - aside from the Pentax FA 28-70 f2.8, which lens is generally thought of as the best in or around this range? So, I am referring only to the latest AUTO FOCUS models available, as I know that there have been many variations over the years. Or if you have a particular favourite of a certain model that exceeds what is currently on the market, please feel free to name that one too. (eg, Tokina ATX Pro II etc). The Tokina 28-70 f2.8? The Sigma 24-70 f2.8 or ? The Tamron 28-75mm f2.8 macro? And, I just discovered that Sigma has two lenses available - they are 28-70 f2.8-4, and a 28-105 f2.8-4. They are only USD$119 and $199 respectively at BH. Anyone have any experience with these? I particularly like the 28-105mm focal length (I have the Pentax 28-105mm FA Powerzoom, and I love it, but at f4-f5.6, it is just too slow), and the Sigma 28-105 f2.8-4 would certainly address the issue of speed that I have with the Pentax FA 28-105, but with these two Sigma lenses being so inexpensive, it makes me wonder why it is the case... Also, how many of the above have macro capabilities? And why is your particular choice your favourite? Bokeh? Sharpness? Flare (or lack of it)? Build quality? AF Speed? Price? Value for money? etc... Also, is f2.8 the fastest anyone has ever seen in a zoom lens of constant aperture? Is there any record of anything faster ever being produced? So, here is my wish list for such a lens - a sharp, nice bokeh'd AUTO FOCUS lens, focal length of 28-105mm, f2.8 constant aperture, less than usd$400. I'm not asking for much, am I?!? lol.

AW: The best 28-70 f2.8 zoom?
Tan, I realise that those are busy moments and that maybe the ability to change the focal length/frame a little indeed can make the difference. I have only bought my first AF camera fairly recently and I have never really worked professionally as a photographer. I do however remember from the occasions that I did photograph a wedding or similar events (are there any?) that I used either the 2.0/35 or the 1.4/50, depending on how cramped the location was. I could have *never* focussed quickly enough with a slower lens (and I would have loved to have a 1.4/35). Sven -Ursprüngliche Nachricht- Von: TMP [mailto:[EMAIL PROTECTED] Gesendet: Samstag, 15. Mai 2004 19:28 An: [EMAIL PROTECTED] Betreff: RE: The best 28-70 f2.8 zoom? Hi Sven! Unfortunately, when shooting Weddings, I find that zooms area necessary evil. Sometimes it is just very impractical to physically walk in closer or move further away from a subject. They become indispensible in many situations. Off the top of my head - an example is the wedding party walking down the aisle. If they are walking toward you, it is not usually possible to take a shot and then turn around and run up the aisle to ensure that you don't crop their heads off as they come closer. The speed issues are for a number of reasons - currently, both of my zooms of this range have apertures of f4-f5.6. Slow. So usually, to achieve the blurred background that I need for most shots, I need to shoot with the lens wide open. Most people will know that when you shoot any lens wide open, it usually results in a softening of the image. So, I am looking for a zoom that is a tad quicker than say f5.6 so that I may shoot at like f4 and know that it isn't going to be completely soft, or wide open. Secondly, most churches are really poorly lit, and despite usually being able to use flash, I like to stop down and use a slow shutter speed to allow much of the ambient light to sneak in. That extra stop or two could make all the difference here in the bride and groom looking as though they have been blasted with a flash, and standing in a black hole, or having them appear to be naturally lit. I do have the FA 50/f1.7 but sometimes it just doesn't cut it when I need that bit of extra reach, or if I need to go wider in a pinch. Another instance is when I am shooting kids - I generally work outside with them, and they tend to run around with me chasing - a nice, fast zoom would be fantastic to have sometimes. I have a fashion photographer friend in NYC who absolutely refuses to buy any lens that is slower than f1.8!! Mostly for the reasons I have mentioned above. He only owns one zoom - it is a 28-80 f2.8 (a Canon of some sort), and he rarely uses it, but for emergencies. When I told him of my lens line up, most of which are quite slow in comparison, he actually laughed and told me that I need to start building a kit like a professional and not like some kid who likes to wave a camera around. He is a harsh, cynical New Yorker (lol!), but I love him for it, as he doesn't mince with words, and he has often expressed things to me that have helped me to improve my work and which normal group of friends and family would never be game enough to come forward and say. I thought about his words for some time, and realised that he is completely right. This is why I have decided that from now on, I will only buy the best lenses that I can possibly afford, and I will wait UNTIL I can afford the best before buying any at all. I do need a zoom of this calliber, but I will be waiting for as long as I need to be able to save the $$$ and buy the best that I can.

Re: OT: Cleaned by first leaf shutter
I have also cleaned some grease from shutter or aperture blades with a cotton swab and some solvent. This works well, as long as you do not soak the whole thing and as long as you understand that you are curing a symptom not the cause. The grease did not just materialise on the blades, but came from inside the lens - from helicoids, rings, levers, whatever. If some has found its way onto the blades, there is more to come... So a real repair requires the whole thing to be taken to pieces. And there is no feeling like seing a bunch of disassembled shutter blades in front of you... Sven Zitat von Collin Brendemuehl [EMAIL PROTECTED]: It takes about an hour. The Ikonta's shutter leaves were oily and sticky. So I grabbed some cotton swabs, and the lighter fluid, and tweezers.

Collin, I feel it would be appropriate if you changed your sig to some short, brilliant, funny or weird thought, quote or whatever, as others do it. The way it is now, it is a list of very, very offensive statements - and I think that you are aware of that. In this sense it is not 'just your sig' but rather provocative and impolite. I don't think that a pissing contest can help here, but hopefully reason can. Do you really *need* this signature line?

Re: DOF and angle of view or focal length (long)
My rule of thumb is that when I use a lens designed for film cameras on the *ist D, I get one stop less DOF as what is engraved on the lens. Example for a 55mm lens: DOF indicator says infinity to 9m for f=11. On the *ist D this will become infinity to 12m as indicated for f=8. However, you get one stop more DOF than using the 'equivalent' focal length on a film camera at the same aperture. Sven Zitat von [EMAIL PROTECTED]: Fra: Jens Bladt [EMAIL PROTECTED] ... Some say, that smaller formats have greater DOF (Photonet). They say that in order to get comparable images, I must use shorter focal length to go with the smaller format, thus achieving greater DOF. They are using circle of confusion (COF) theories to support their point of view. If you want the same field of view, that is correct. I (and Photozone) say, that smaller formats only show a part of the image, captured by a specific focal lenght. If I shoot the same scene twice with the same camera, same lens (focal length( and same aperture and focus point, you will get identical images on let's say APS and 35mm film - that is for the part, that is covered by the smaller format (e.i. APS). I say that the DOF of these two identical images - is exactly the same. I say that focal length, aperure and focal distance determins the DOF. If field of view is unimportant, that is correct. The APS size sensor simply crops the image. IMO COF theories are somewhat subjective, because the point to where a point looks like a disc, depends on the degree of enlargement. I think that the smaller image, captured by a shorter focal length needs more enlargement, thus less appearing less sharp. What is right and wrong here? Both, depending on you priorities. If angle of view is important you say the first, if DOF is more important you say the latter. In addition, as you say, the degree of enlargement also plays a part, along with resolution/diffraction limits etc. This image: http://foto.no/cgi-bin/bildekritikk/vis_bilde.cgi?id=13611 is impossible to make with an APS size sensor, because of the combination of shallow DOF and field of view. This was made using a 28mm @ 1:2.0. A corresponding 18mm will not be able to make the large difference between COF in focus and in the background. Compare images made with MF and APS formats and this is much more evident. DagT
Re: European PDML Meeting 2004
I could offer to find a nice place to gather in the afternoon, after the Photokina visit - to put some cameras on the table and do some Pentax-talk.

AW: daddy-D
Another way would be (or have been) to incorporate the current 'green button' function into the shutter release, IOW to stop-down-and-meter in the instance before the shutter is released. This would add a small delay between pressing the shutter release and the actual shutter operation but would give automatic (stop down) metering.

Marz 2004 21:17 An: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Betreff: daddy-D John had a complicated method for getting a *istD successor to correctly operate K and M lenses with camera-aperture-control. Nikon has a similar scheme in the D2h to allow matrix metering and such with older CPU-less lenses, which is odd since the FA of 1983 could do it without the manual input of information. Wouldn't it be simpler to build a daddy-D with an aperture-tracking-tab so that it could meter correctly at full aperture, but NOT attempt to overcome the difference in aperture-lever travel between K/M and A/F/FA lens lines. It would let you use your K and M lenses in aperture-priority and manual just like you always did, and more modern lenses with all the newfangled modes. Pentax could top this off by re-issuing some of the older lenses in FA variants for people who just have to have P mode with their 18/3.5. If the camera knows when it's got an A or better lens mounted due to electronic communication, it could refuse to go into advanced exposure modes unless it found a modern lens attached--just give a snippy error message.

Refconverter M
The postman yesterday brought a nice Refconverter M to my door. A cute little thing... The manual says that once the diopter is set to match your eyes, the setting does not need to be altered when magnification is switched between 1x and 2x. This I think is either a mistake in the manual or the one I have is not as mint as it looks... I have to turn the diopter A LOT to get a sharp picture in both settings. Does anybody use this accessory and can confirm? Thanks, Sven

Re: Rolleiflex Knowledge
That would really depend on the model also (DB8/9 does not indicate the model ... and Rollei made various TLRs with 2.8 Planars from the early fifties to the mid seventies).

Links to 'My PAW' sites
Wouldn't it be nice if there was a web page with a compilation of links to all the sites where list members store their PAWs (something like an extra column to the PUG list of member's sites)? I then could bookmark only this page and browse from there through all the PAWs every week. Good examples would certainly continue to be mentioned and discussed here, but this would remove the need to mention every single one every week (and this would remove some traffic). What do you think? Sven Zitat von David Mann [EMAIL PROTECTED]: Hi all, After putting my last couple of PAW images up, I decided to set up a script-based site to make it easier to add pictures.

Re: Digicam Slide Duplicator / Scanner
Do you remember which setup gave you the full frame? I have also spent an evening juggling with 35, 40, 50 and 55 mm lenses, reverse rings and extension tubes and did not find a good setup (using the x1 slide copier). I thought the only way would be to use the slide holder that attaches to the bellows (that I don't have).

AW: Long exposures on auto
I have also used the LX for long time AE night shots, up to probably 4 or 5 minutes and I have also wondered whether Pentax has built in some compensation for the reciprocity error that no doubt exists for such long exposures. As the Impresa is a print film and from your description of the 'milky look' I guess that you judge camera exposure from the prints that you got - which might not tell you the true story... What you have to keep in mind, is that the camera exposes for an 'average grey' exposure and for a typical night shot you do not want this, usually. In a scene with a lot of 'black night' and some bright spots the camera meter would probably be mistaken by the black and overexpose - to keep the night impression you would need to correct the exposure by -1 or so. Now with print film this becomes even worse, as the printer will 'automatically' underexpose (leave grey) the areas that you exposed to be plain black. Correct prints from such a negative you will only get after complaining - or if you pay for a hand print up front. Sven -Ursprungliche Nachricht- Von: Stephen Moore [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 26. Februar 2004 17:28 An: Pentax List Betreff: LX: Long exposures on auto A question for the LXers: What's the longest (ballpark figure) successful exposure you've made using the LX's automatic, direct-metering mode? Although I've grown to trust the AE mode in conventional photo situations, around New Year's I tried out its low- light capabilities for the first time. I was using Konica Impresa 50 and a Vivitar Series 1 105/2.5 macro at f/8 to shoot the Christmas tree and some of its ornaments. During the day, with tree lights on and some daylight selectively let in through drawn drapes, the LX was choosing exposures on the order of 10-20 seconds and producing very good images. After dark, however, using only the tree lights, times were running to 4-5 minutes, sometimes more. Also tried some whole-tree shots, using a flashlight to paint the tree and selected ornaments. All these shots came back with a severe case of that milky underexposed look (but, in tribute to the Impresa 50, not at all grainy.) The light-painting shots were better, but still spoiled by the underexposed background. So, did I run into reciprocity failure? Is there any way to let the LX still do its thing yet avoid the problem? Any other LX-specific low-light tips would be much appreciated. Thanks, Stephen Moore
