RE: Next body after P30?
I own a Super A as well as a P30 and P50. It's true that the (earlier) Super A is superior to the other two (TTL flash and shutter priority). One thing I like ablut both P30 and P50 is the very soft release. The P50 has a beautiful design as well.

Hi Peter I'd agree with Joe. The Super A / Super Program is a great manual camera. Apart from the LX, it was the most sophisticated manual camera that Pentax produced and it picked up a swag of well deserved awards. I've seen good examples offered on ebay so you could probably pick one up at a reasonable cost. It features program, aperture priority, shutter priority and metered manual exposure modes as well as TTL flash (program and shutter priority only available with 'A' series manual lenses). Also has depth of field preview, exposure compensation and a PC flash connector socket. I've been using one for many years and I still use it regularly even though I have more recent models. The P50/P5 is also good as a step up from the P30. Although not as full featured as the Super A, it is (in my opinion anyway), one of the best handling models that Pentax produced - it really feels good to use. It has 'landscape' and 'speed' program modes as well as aperture priority and metered manual. No TTL flash. It doesn't provide for manual setting of film speed - DX only (like the P30) but if you feel the need to change the rated film speed, you can get around this by using the exposure compensation facility (unlike the P30). I've never used the MZ-M so I can't comment on that one.

Re: Next body after P30?
Hi, Peter, The next step up is probably a brief step back chronologically, to the Super Program/Super A, which is a better and more advanced body than the P30t, with the sole exception of a lack of an exposure lock/hold button. It has TTL flash and program/aperture priority/shutter priority/manual modes along with program flash and TTL flash modes. It doesn't set the film speed for you, but this means you can expose film at other than its rated speed, and it has a really nice viewfinder with full information (at least in program shutter priority mode) that's a pleasure to use for manual focusing. Other directions to go may be the slightly harder to find P5/P50, which I believe at least has a choice of program modes, or the Program A/Program Plus, which is the budget model of the Super Program. In autofocus, the SF1n/SFXn is actually very nice for manual focusing, with the best Pentax viewfinder (all glass) of the autofocus bodies until the MZ-S came along. Most of the autofocus bodies are fine for manual focusing, though there are no split-prism or microprism focusing aids. The cameras can give you a beep or a viewfinder indicator for proper focus with manual focus lenses. Most of the PZ/Z series and the ZX/MZ series of autofocus bodies will give you multi-segment metering if you have manual focus A lenses and several have spot metering and other nice features that work just fine with manual focus lenses. The sole current manual-focus body, the ZX-M/MZ-M, is quite nice, although very small and light, and while the viewfinder is much smaller than the ME Super/Super Program's, it does have the split image/microprism focusing aid.

Re: P30 and AF201SA
I would suggest that it works the same way; that the aperture and speed will be set automatically in AE mode. But if you have the shutter set below 1/100 it will not be changed - apparently. The P30 film speed is ISO 100 without a film in the camera. But why not just put one in? Or an empty cassette?

Re: P30 vs. Super program (Super A)?
I've posted about this separately, but it bears re-asking. Do you refer to the speed of the X-position of the mode dial, or the speed when the shutter-speed selector is on 1/125sec? I would frequently use that setting if I wanted to mix TTL ambient and OTF-flash metering (the X-position is unmetered, OTF flash is always on depending on the flash unit connected). I never got half-framing. The X-position isn't a battery-less position, unlike the ME Super AFAIK, so the reason for this is beyond my ken, but if I had to guess then I'd say that 1/125sec doesn't have enough 'dwell' (to steal a motoring term) to permit slower electronic flashes. For instance my Metz 60CT-1 has full power duration of 1/400sec, and the big Hensel 3200 and 600 joule packs I formerly used burned for about 1/100sec at high powers (requiring 1/60sec or longer). regards, Anthony Farr - Original Message - From: Lon Williamson [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, 12 June 2003 8:04 PM Subject: Re: P30 vs. Super program (Super A)?

Re: P30 vs. Super program (Super A)?
I don't think this is the case, Anthony. The shutter speed curve has a wiggle right at 125th that happens on flash synch or on manual. To me, this is no big deal. However, someone questing for a perfect within a third stop exposure would probably have to factor it in. Anthony Farr wrote: I read this often, and yet those times that I have shot with flash at a selected 1/125sec, rather than at the X-position of the mode selector, I've never got any 'half-framing'.

Re: P30 in 2003?
About two years ago I got a brand new P30T from a dealer in LA. He had put one on eBay and I emailed asking if he had any more. He had and I paid about $120 I think. Its a fine camera and with a good lens I cannot see how other cameras can 'run rings' around it? Perhaps you'd be able to find a new one as well? I like mine and have a slightly older one, a P30, as well. They are more automatic than any other cameras I've used over the last 50 years or so and if I had to buy something else it would be an MZ-S.

Re: P30 in 2003?
The bright viewfinder was the only thing I missed when I sold the P30t ( had it for some months). And I think the sound of the MZ-M-motor is not more bothering than the CLACKK of the P30t-shutter. BTW: Is the viewfinder of the MZ-S brighter than that of the MZ-M (and the MZ5-N, - I think it's the same)? I am sure you can evaluate that, Alan, am I right? I hade the P50 which is the elder brother of the P30. It has brighter and better viewfinder than the supposed should be good Super A/Program. Personally, I would not consider any MZ/ZX model if you plan to use manual focus, except the MZ-S. The reason is that they all have highly distorted, low magnification, and difficult to manual focus viewfinders. I believe the problem lies at their poor quality uncoated plastic eyepieces which distort everything you see. Pentax abandoned the good old multicoated glass eyepieces since the Z/PZ MZ/ZX series, until the MZ-S. For this reason, if you want AF body with good viewfinder, MZ-S is your only choice (Z-1p is ok too, but ok only). However, at 0.75X magnification, it is still lower than the P30 that you had. But it did not seem to be a problem the last time I tried it with some manual focus lenses. MX has the highest viewfinder magnification, ME/ME Super 2nd. I currently use the MZ-M screen in the MX and the viefinder is bight and big. :-) regards, Alan Chan _ MSN 8 helps eliminate e-mail viruses.

However, as Pentax have proven time and again, no camera should be too perfect. So they installed a few things to balance things out. 1) Dim coarse focus screen (worse then P50). 2) Relatively low viewfinder magnification in its era. 3) Noise mirror/shutter (worse than P50, don't even touch the Motor Drive A). 4) Too much vibration from the mirror/shutter (worse than P50). However, it is the only manual focus camera with 4 expoure modes - manual, auto, aperture priority shutter priority. It is also the only one with TTL flash beside the LX. This model is also quite reliable. Dirt self-timer shutter release button contacts are common problem on used models, but they don't require new parts to fix. The area near the semi-transparent plastic on the top plate is the weak part so don't bang on it. IMHO, if you expect super sharp images handheld, get the ME Super or MX. The Super A will disappoint you due to the mirror flip.

The P30 and Land's experiment
Long ago, when he was working on the development of colour film, Land did an interesting experiment. He took two pictures of the same scene with BW film, one through a green filter and one through red. The pictures were then projected on a screen from two different projectors: one with a green filter and one with a red filter over the lens. The result was a full colour image. In 1963 I found a description of this experiment in Scientific American and did the experiment myself. Sure enough it worked. How and why? I don't remember the details, or the explanation, but it had much to do with the human eye and brain and less to do with the wavelength of the light involved. I'm going to try the same experiment, but instead of projectors I'm going to try to do something on my screen with Photoshop and layers. It may not be possible, but will give me something to mess with between now and when things get back to normal in a week or so. The most interesting thing about the whole experiment is that there were shades of blue in the images. I'm going to pick up some BW film for my P30, before the shops shut, and have a go at this over the holidays.

Don, Thanks for the reference, I'll have to look for some of the articles. Land and Polaroid did some interesting stuff with color perception. Regards, Bob S. [EMAIL PROTECTED] writes: Long ago, when he was working on the development of colour film, Land did an interesting experiment.

It may not be possible, but will give me something to mess with between now and when things get back to normal in a week or so. The most interesting thing about the whole experiment is that there were shades of blue in the images.

Re: The P30 and Land's experiment
Prokudin-Gorskii used a similar method to make color photos across imperial Russian in the late 19th and early 20th century. His work was chronicled in a book unfortunately I don't recall the name, Evan From: Dr E D F Williams Subject: The P30 and Land's experiment Long ago, when he was working on the development of colour film, Land did an interesting experiment.

Re: The P30 and Land's experiment
IIRC that was the same method used by NASA to obtain color photos from the Mars lander missions. Bill
Vs: The P30 and Land's experiment
This is an old experiment, from the 19th century, I think. It works because the filters are not perfect, they let through some light that they are supposed not to. That´s why Maxwell succeeded.

Flash for P30 and SPII
I have a third party brand (TUMAX) AF flash for my Z1P. Could I use it with P30 and old Spotmatic SPII?

K28/3.5 P30 for 120 US$
Hello!Just run into a P30 (P3) with K28/3.5 in some sort of pawnshop.I was looking for this lens for a long time to replace my A28/2.8. The camera is in perfect working condition, very clean inside,some paint is missing on the edges of metal bottom plate.The lens is surprisingly totally dust free inside - it was very dusty outside and had some goo from some sticky tape.There is some paint missing on the aperture ring.It is perfect mechanically; it only has couple of cleaning marks on front elementthat are so tiny, that at first, I thought that they were some dust particles. I paid 120 US$ for everything.Was the price OK and how much these things go for? I was thinking of selling P30 with my old A28/2.8.Or maybe I'll keep them as a cheap pointshoot camera for some rough trips! AleksandarJoin the worlds largest e-mail service with MSN Hotmail.

P30 and P30t macro photography
Hi all, I've been here, but off the list for a while. Now I'm outside crawling about taking pictures of flowers, many being only 2-3mm diameter, as usual. Macro Photography with P30 and P30t: Equipment: Pentax P30 and P30t, Sigma Macro 50mm, several Pentax lenses with Soligor macro converter, small shoe-mounted flash gun (name lost), aluminium reflectors, Fuji and Ferrania negative colour. Processing Tetenal Colortex C-41; s/s tanks in thermostat controlled water-bath. I've devised a new, double, flash reflector. One part goes on top of the flash gun with Velcro and the second part is fastened to the tripod socket - with an adapter so the tripod can still be used. As before the reflectors are made of 0.5mm sheet aluminium polished to remove blemishes and then matted with 'Putkimies' (Pipe-man or plumber) drain cleaner. This drain cleaner contains 10% NaOH and does a creditable job. It takes a little longer than a more concentrated solution, but its right here under the kitchen sink. This time the top reflector is more or less 'T' shaped, extends 130mm from the front of the flash and is directly above the object when the lens is fully extended. The front is bent down and the two 'wings' are curved left and right. The shape is parabolic and I did a lot of calculating to get the angles right. The light is now reflected downwards at about 50 degrees and concentrates (I won't say focuses) on the object. The lower reflector (flat) bounces back some of the light so that the shadows are not as pronounced as they were with only a top reflector. Naturally when I designed this thing I considered only a single ray. The flash, to start with, scatters the light widely. The attached top reflector does more and the light by the time it reaches the object is very diffuse. The light coming up from the lower reflector is much weaker. Using a Seconic flash meter I get a nice f22 at 1:1 with 200 asa film at the subject position. A picture taken with ambient light under these conditions would require four or more times the exposure on a sunny day, even more under cloud. The flash, set on automatic, serves to freeze movement nicely because the ambient contribution to exposure is small. The busiest bees and flies, not to mention wind-blown blooms, come out nice and sharp. I'll be putting a picture of this contraption on my website in a week or so and anyone wanting to see it let me know and I'll give you the address of the directory.

Re: what a deal! (damaged P30 K135/2.5)
Mishka, All it takes is an ebay id to bid, and some perseverance. I saw this yesterday and never checked the details...just let it float by! For $46, it is a real deal for the 135mm. Didn't you want one of those? Regards, Bob S. [EMAIL PROTECTED] writes: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=1346937180 - This message is from the Pentax-Discuss Mail List.
