 Looks better than pretty darned good to me - unless there are some
 really strong negative reports from the GFM crowd I'll be buying one.

I'm trying very hard to not turn into a fanboy over this camera.
It would be too embarassing, and bad for the surly image I try to cultivate.


 The frame rate is quite a big deal for me, too.  I really liked
 the responsiveness of the PZ-1p (4+fps), even though I mostly
 used it in single-frame mode; the faster frame rate results in
 a shorter viewfinder blackout time, and the camera is ready for
 another shot sooner; I occasionally find myself trying to take
 the next shot before the (3fps) K10D is ready.

This is really the biggie for me. I really like a responsive camera, and 
higher frame rates seem to go hand in hand with that. I was trying to 
explain to someone over on forumneurotica that just because I wanted a 
camera that had 5fps didn't mean that I wanted to use it at that speed.
They just presume that one wants it so as to be a tail gunner.

Hmmm...I shoot lots of weddings each year, along with lots of paid
portraits and family groupings - almost always flash fill.  The 1/250
would be nicer, but the 1/180 is not a deal breaker for me.  I
generally set the flash to handle high speed and then watch my
shutter speed - using ISO somewhat to help control things.  Not a
huge issue, just a small nice to have, in my book.

 You're missing the fact that the amount of flash exposure you can work
 into a shot is dependent only on the f stop. So if I shoot a backlit
 portrait outdoors at f5.6, 1.250th, I can fill flash in at that 5.6 value.
 If I'm forced to stop down to f6.7 because I can't go beyond 1/180th in
 shutter speed, I lose flash exposure and increase DOF. Ideally, I'd like to
 have flash synch up to 1/1000th, but that's  complex and cost;y. And
 high-speed synch doesn't help much, because  the flash power is greatly
 diminished by multiple firings.
 Paul

 Of course, with hummingbirds, it's even worse. Why, at 1/180th, the
 hummingbird's wings have gone through a whole 38% of a stroke. With
 1/250th,
 that'd be reduced to a mere 28%.

RE: K20D as Scanner

with a dslr and its instant results review, it should be
fairly easy to use a pair of flash and be able to adjust
them for even lighting. that way you eliminate possible
motion blur from long shutter speeds and will be able
to use smaller fstops most likely too. But flatbed scanning is better
I would think.

Subject: Oh another K-7 thread...



Hi list,

Sorry for opening a new K-7 thread... I just tought to share my thoughts 
with you...


So... K-7. When I first saw the pictures it was a beauty for me. The first 
thing that crossed my mind is I MUST HAVE ONE (yeah with all-caps :D). 
The K-7 is a very nice and very stylish camera and it brings back the old 
style when engineers designed machines with ruler and bows. Personally I 
dislike the now trendy 'everything is rounded' style that rules the 
designs nowadays (cars, computers, phones etc). But, oh-well, Nikon has 
quite similar design with D3 and D700, so it's not that unique, yet Pentax 
made it much more stylish than Nikon (IMHO).


Then as the first set of so-called-specifications came the K-7 was still a 
promising camera. 1/250 Synch and 1/8000 Shutter, Better AF, HD-Video, AF 
Assist light, etc. All in all the K-7 was the nice big red balloon that 
everyone wants :)


But as time passed by the specifications turned to be false or 
not-that-nice. 1/250 went back to 1/180, Better AF -like the sensor- is 
just an Improved (but same) SAFOX VII, HD-Video is only 720 lines and 
motion JPEG...


And now the test shots on the official page... Terrible. First the girl... 
totally lacks sharpness for me and well the dynamic range of the photo 
seems to me not that awesome. Then same applies to almost all shots. And 
in the end the last shot made with the 12-24. Terrible CA. One of the new 
features is the CA correction and this how they market it?


So all in all I am very disappointed with the K-7 as the new flagship 
model. It's nothing more just the K20D with a class-closing (or how should 
I call the opposite of class leading? :D) HD video feature and tweaked 
features. The nice big red balloon seems to be popped out...


But don't get me wrong... I still love the K20D and the Pentax Side of 
Life :)

Re: K20D as Scanner

2009-05-22 Thread Joseph McAllister
I've done the same thing, Ken. It takes so long to scan a print or  
negative on a scanner, but I've used (for general use - family photos,  
etc) setting a print or Polaroid print on the bed of a copy stand; a  
tripod and an old glass contact print frame; an old Saunders contact  
sheet frame with the plastic torn off and Goo Gone cleaned (whew!).  
These options take much less than a minute per setup, shot RAW, minor  
corrections in Aperture, and I've been very pleased with the results,  
from those Polaroids to 100 year old deckled edge prints.

RE: K20D as Scanner

2009-05-22 Thread JC OConnell
The length of time it takes to scan a document is solely dependent
on and proportional to the dpi setting and the size of the document, it
would not take anywhere near the highest dpi settings to
match an optical method of duplication IMHO and if you wanted the
highest possible
quality, a scanner could exceed any optical/camera method on large (
5x7, 8x10 ) documents.

 I think you're right. Here is the help. Practically I can of course
 translate all of it, but it will take ages. Few random points:

 1. The camera sensor seems to be totally new. They have played with the
 micro lenses to increase actual area of a single pixel. The reviewer also
 mentions that this new micro lens design makes it work better with film
 lenses and it allows for wider range of angles of falling light.

 2. The picture modes (or whatever is the name) can now be fine tuned for
 separate contrast rendition in bright and dark areas.

 3. They mention that this camera is set to compete face to face (or hmmm,
 lens mount to lens mount) with Nikon D300, Canon EOS 50D, Sony Alpha 700 and
 Olympus E-3.

 4. All in all, consider that instead of reading through numerous pages of
 DPReview review (all the description stuff, not testing) you got it
 presented to you by someone in front of a video camera.

 Perhaps if I look at it half dozen times I'd notice more details that might
 have been omitted in the web based texts, but in general - this is yet
 another description of the new camera.

 Having seen that video that Cotty shown I as well might wanna buy this one.
 I do want to shoot short videos in general and short videos of my girls in
 particular.

 Cheers.

Jostein, greetings and salutations on the oncoming trip. It should

Humbly, I suggest that you don't take DA* 300 lens as you have DA* 
60-250 that appears to be quite stellar. I don't think that 50 mm will 
make any difference here. FA* 600 is entirely different of course.


It would seem more desirable to prefer K-7/K-20 over K-20/K-10. The

Other than that - I think you should simply put some cash towards 
hauling more weight. It seems inevitable at this point.

Why is the K-7 the K-7 instead of the K7 or K7D?

That first image is spectacular but I think the pale sky spoils the
second one.

By the way I took a quick look through some of the work in your

the surface (it would take me about a year to do the galleries justice!)
 I like the Ireland work and I spotted a Banksia menziesii among your

Re: Speaking of airplanes an tripods...

2009-05-22 Thread AlunFoto
Thanks to all for your recommendations! Much appreciated.

There are some things I'm now quite certain of:
- There's no way I will let optics travel as checked-in luggage. :-)
- The 600mm has to come along. Thanks for firming my resolve there.
- I will have to make a thorough comparison of the 60-250
  and the 300 to decide if both will go.
- The total weight of the gear will be a problem.
  Excluding the 300, the photobag is still at 23 kg.

I was informed yesterday that our international flights will be with
British Airways, and with warnings that our hand luggage may be
weighed at Heathrow. That didn't happen when we travelled to Newcastle
last Easter, but on the other hand I didn't bring the 600 then.
The recommendation from the guide is to have a photo vest with plenty
of pockets to stuff things like normal zooms, batteries, flash, etc.,
in before the bag goes on the scale. He claims to have got away with
shouldering his 500/4 as a personal item too... :-)

I have researched the possibility of posting a travel log to my blog,
and apparently it's possible to send clean-text emails through
satellite link from the ship. No graphics, though. So pictures will
have to wait until I get back.

If I'm forced to stop down to f6.7 because I can't go beyond

nothing, but it's still only two inches.

Ideally, I'd like to have flash synch up to 1/1000th, but that's

Right, I understand that going from 0.0056s to 0.0010s would be  
useful.

That's two and a half stops better, and in the example above, you're
shooting at f/2.8 and have more than halved your DOF, down to about  
6.



And high-speed synch doesn't help much, because the flash power is  
greatly

diminished by multiple firings.


So, improved noise performance should help just as well, right? I  
wouldn't
be surprised at all if the sensor refinements gain you your half

HSS doesn't buy you any extra flash output, in fact it reduces it on many 
models of flash. (the same energy must be spread over a range of exposures 
to build up the frame, so you don't get full power in each slice).


Basically once you hit max flash output (or the max you want to use for 
acceptable recycle times), the only way to increase the flash's contribution 
is to reduce ambient, ie faster shutter speed (changing aperture affects 
both flash and ambient).


As awesome as the K7 does look, this is the thing I really wanted to see 
improved, and what disappoints me most about the specs.  Especially as they 
took the opporunity to improve the FPS and max shutter, so presumably a new 
shutter mechanism, without addressing this basic issue.


Also, I don't see why they don't offer an electronic shutter on 1/180th 
exposures, some of the Nikon DSLRs have done this (was it the D70?), and it 
allows flash sync at any shutter speed - the mechanical shutter never goes 
faster than 1/250th (or whatever) and the quicker exposure is done 
electronically.  There may be some technical reason not to offer ths, but 
one would think if you can do live view (ie, readout during exposure), 
surely electronic shutter isn't that different.

I too am disappointed at the 1/180 flash sync speed. The difference
between 1/180 and 1/250 can indeed be significant, making the
difference between a shot that's saleable and one that isn't. I was
once shooting finish line photos in a marathon which had the runners
coming in with the sun at their backs -- poor planning on the part of
the race organizers, eh? ;-) I was using the PZ-1p at the time and
could see the difference 1/250 made between marginally acceptable
and completely unacceptable or between acceptable and good. 
(And full sun backlight makes the power loss of Hish Speed Sync flash
unacceptable.)

Or, put another way: The difference between 1/180 sync and 1/250 may
not be huge, but in some circumstances it can be *much* bigger than
the difference between a consumer-grade kit lens and the thousand
dollar pro lens so many of us (justly) lust over.

To put some numbers on it: the Metz 48 AF-1 has a GN of 35 at 50mm-e @ ISO

 Im not talking about the current or near future lenses,
 Im talking about the long run. It only makes sense that
 things that can be corrected in the body rather than
 with optics may be cheaper way to go but you would have
 to use new bodies only with those optically uncorrected lenses.
[434 lines, snipped]

Computationally correcting the optics will be expensive in terms of time
for the camera to perform the processing (several seconds); the lens
reviews will be harsh, so going first on this would be bad for sales;
the ability to correct computationally will depend on *higher* quality
control standards in manufacture, since the information provided on each
lens will have to be very accurate or you're just having the camera
apply funky blur.

I don't think there's an economic win in there anywhere.  Computational
correction makes a lot of sense for those cases where the optical design
can't manage to get things precisely right, either because it's a kit
lens or no one wants a 10 k USD 12mm Ltd. so they didn't make it.

the biggest problem with slow sync speeds is you
end up having to use small fstops to get the
ambient light exposure correct and that robs you
of flash range and/or flash fill ratio, but
half stop is half a stop, its a moderate improvement.
Compared to 1/60 in the old days 1/250
is fantastic though.

Re: K20D as Scanner

2009-05-22 Thread Walter Hamler
I just purchased an Epson Perfection V30 from NewEgg.com on sale for
less than 50 bucks shipped. I have been using it for several days now
making copies of old (50 years plus for some) 8x10 BW and Color
prints for which the negs are long gone. I am very pleased with the
quality and convenience. The quality is several stages better than
what my old Canon 660U provided, and I thought it was a great scanner.
But 8 years of technology go a long way!

I have also copied old prints using my K20, as Ken did. The results
were quick and painless, and the resulting images are as good as with
the Epson. It would totally depend on the situation at hand. If I
didn't have a scanner I seriously doubt that I would buy one if I
seldom needed or wanted one, especially when I knew that the dslr
would do just as well.

RE: K20D as Scanner

2009-05-22 Thread JC OConnell
I seriously doubt you will ever get even close the quality of a 2000dpi
scan of a full size super sharp 8x10
document/print with a camera and lens. It all depends on the dpi you
use. For example at 2000
dpi, you get approx 4 MPixel per square inch, and using 8x10 print, that
would yeild
a 320 MEGAPIXEL image. Youll never get close to that with any current
digital slrs even
if you had a perfect lens. I have two epson scanners, one does 2400 dpi,
and one
does 3200dpi so at 2000dpi they are not even being pushed to their
limits. Even if you
only use 1200dpi nearly all scanners are capable, your still talking 115
MP image of an 8x10 with a scanner.
The other factor to consider is when scanning photos or documents, they
do not have nearly
as great a dynamic range as film does, so getting a scanner to handle
the dynamic
range of the photo or document without clipping is not very difficult to
do.

Note both Panasonic and Hasselblad are already doing this. In
Panasonic's case, without any noticeable hit to processing speed.

Panny's choice to do this comes primarily down to getting the most
lens possible in a compact package. They're choosing speed and
resolution over distortion correction and fixing the latter in-camera
(or at the RAW conversion stage). This is what let them do the
24-60mm-e f2-f2.8 zoom in the LX3 and allowed the G Vario 14-45 OIS
for the G1 to be so small and still contain IS.

Hasselblad just cheaped out on their 28mm for the H-series. Of course
this is one case where their choice allowed a noticably cheaper lens
than the competition. The Mamiya 28mm is significantly more expensive,
but is also fully corrected and actually covers a 645 frame, the Hassy
only covers a sub-645 sensor and only works on the vendor-locked H3D
bodies, not the H1, H2 or Fuji GX645 (aka H1) bodies and thus only
with Hassy/Imacon backs.

Subject: RE: K20D as Scanner


 The length of time it takes to scan a document is solely dependent
 on and proportional to the dpi setting and the size of the document, it
 would not take anywhere near the highest dpi settings to
 match an optical method of duplication IMHO and if you wanted the
 highest possible
 quality, a scanner could exceed any optical/camera method on large (
 5x7, 8x10 ) documents.


Printer resolution is in the 300 ppi (Fuji) to 360 ppi (Epson) range.

An 8x10 file optimized for an Epson printer will be 2880 x 3600 pixels.
If your prints are being done at what passes for a photolab these days, the
resolution requirements are much lower, in the 2400 x 300 pixel range
(Fuji), Noritsu is slightly higher (320 ppi).
The output from a K20 is 4672 x 3104, ample resolution to do a 1:1 copy of
an 8x10 print.
For the application that Ken was using the camera for, the K20 has ample
resolution, and would likely be faster than a flatbed scanner in real terms.
There's no real point in having a higher resolution file if all you are
going to be doing with it is discarding unused pixels at the printing stage.
There is little point in scanning a print at higher than 400 ppi, as few if 
any photographic prints will exceed that resolution. At Kodak school, I was 
told that photographic paper doesn't hold more then ~10-12 lpmm of 
resolution, and that scanning at any more than 300 ppi is not gaining much, 
if anything, in terms of real detail, but it does increase the amount of 
post processing you need to do as you scan more and more paper defects as 
scan resolution increases.
Combine this with the fact that most prints aren't taken with the best 
cameras, the best lenses, or the finest grained film, and there really isn't 
any advantage to a flatbed scanner over a modern 14mp or greater DSLR in 
terms of image quality when copying prints.

Actually, you are completely wrong on that assumption.

Apparently I should have written a shorter post to allow you to soak it all 
up. Older BW prints will not exceed 300 ppi resolution, the paper 
resolution just isn't higher than that, and as a general rule, resolution 
will be far less because few people used the best cameras and best 
technique, and the drug store printing that was done back then was all over 
the place for sharpness as well.

John, there isn't much point in continuing this. This is, to a great extent

2009-05-22 Thread Scott Loveless
For those of you who have a Canon 8400, 8600 or 8800 scanner,
betterscanning.com has some new medium format film holders for us.
They're kinda pricey at about $80, but based on what I've seen from
these film holders on Epson scanners, they're well worth the money.

http://www.betterscanning.com/scanning/canon8xxx.html  (I have no
affiliation, but I did beg and plead for one of these.)  I'll be
ordering one soon.

If you'd like a copy of the announcement email please contact me off
list.  It's kinda long and I'm sure Doug would rather I not clog his
tubes.

 Compared to 1/60 in the old days 1/250

I use their Epson holders and ANR inserts. Worth every penny I paid
for them. I HIGHLY recommend getting ANR glass inserts with the
holders though, using them is much less hassle than the T-stops
(little plastic wedge holders that come with the film holder) and
pretty much guarantees flat film when scanning.

 this makes no sense, one has to assume these and most

 and the resolution of said prints is going to be higher
 than modern digital 300 to 360 dpi prints.



Actually, you are completely wrong on that assumption.

Apparently I should have written a shorter post to allow you to soak it
all 
up. Older BW prints will not exceed 300 ppi resolution, the paper 
resolution just isn't higher than that, and as a general rule,
resolution 
will be far less because few people used the best cameras and best 
technique, and the drug store printing that was done back then was all
over 
the place for sharpness as well.

John, there isn't much point in continuing this. This is, to a great
extent 
what I did for a living up until a few years ago, I know of what I
speak.

When they went to metal horizontal shutters, they got a nominal increase in

Good, our work is done.

Seriously, I'm very encouraged by this camera.  Pentax is a small company 
competing with much a lot of pre-established opinions about what they are and 
what their competitors are.  This is a very well built camera with many 
genuinely useful features and a reasonable collection of good lenses.  This is 
all I want Pentax to be.  My only fear is them actually staying in business, 
but I think the pro/enthusiast level is probably right for them.

 Why not? The K-7 is only a bit better speced than the K20D.   
 Delete  the
 video capability, add improved autofocus and perhaps even more low   
 light
 capability. Aim it at a more serious photographer. I wouldn't be
 surprised to see such a camera.

 I'm actually seeing some pretty major (on paper) improvements over  
 the K20.
 The frame rate increase is huge, the buffer is significantly larger,  
 the
 extra 2 channels of pipeline from sensor to image processor is a big  
 step.
 Removing the sensor from dust removal and going to ultrasonic should  
 make
 the dust removal more effective.
 They are giving it another stop or so of SR effectiveness, and it  
 looks like
 the built in flash, as much as I hate the things, actually has enough
 seperation from the lens to be useful.
 This doesn't even start to address some of the things they've done  
 in the
 menu system, such as allowing imbedded copyright data right out of the
 camera and the fine tuning ability that they have applied to the  
 sensor WRT
 composition, though we'll see how useful this really is.
 Finally, a 100% viewfinder. This will be a joy after years of using
 innacurate viewfinders. I think the last accurate finder I used was  
 in my
 Nikon F3. Even the LX isn't 100%.

 The K20 is a decent camera with some major weaknesses, this one  
 looks like
 it should be the real deal, though I am sure some minor quibbles  
 will show
 up.
 The only question I have is how soon can I have one delivered?

even after development. I have some contact prints made from 8x10 negs
that the details look really sharp even under a loupe, way beyond human

vision in the range of 300dpi. The maximum paper resolution was not

Hell, there are probably literary journals you could publish this thing in.  
The good part is that no actual speaker of the English language would ever 
think this is anything but a bad yet funny translation.

I just want to sincerely thank you guys for finding that horrendous
spam mash-up of my review. I'd never noticed that pictips.com site
before, but it is grabbing all my blog posts and reconstituting them
with gibberish, and this is quite maddening to see your own writing
thrown through that blender.

I've written the Whois contact for the site and asked them to remove
anything they've grabbed from my blog (ok1000pentax.com), but I doubt
I'm going to get a reply. They must have some sort of auto-harvester
that does all this work for them while they go off and grab candy from
babies. I can't imagine a human personally editing the sort of word
salad they republish then going home to sleep peacefully at night. But
weirder things are known to happen.

Thanks again!

 Good, our work is done.

 Seriously, I'm very encouraged by this camera.  Pentax is a small company 
 competing with much a lot of pre-established opinions about what they are 
 and what their competitors are.  This is a very well built camera with 
 many genuinely useful features and a reasonable collection of good lenses. 
 This is all I want Pentax to be.  My only fear is them actually staying in 
 business, but I think the pro/enthusiast level is probably right for them.

It's a return to their 1980s heyday when they were putting out smallish but 
very competent cameras that sold like hotcakes. I think it's a really good 
move for them. The market of high performance cameras has been populated by 
beheamoths for far too long.

SMC-A 70-210/4 on digital and a few others...

2009-05-22 Thread JC OConnell
I posted this link earlier in the week but I think I 
have finally got my website cleared by
google again.

This has some sample shots with the
SMC-A 70/210 lens on Pentax DSLR as promised.
The lens is excellent on digital, no
visible CA or distortion problems and very sharp.

http://www.jchriso.com/boca/boca05152009.htm

theres also some other shots on the page
taken with other vintage telephotos from Pentax.
The smck85-210/3.5 is not as sharp as the 70-210
in the corners. The smcK200/2.5 has some minor
issues with CA but otherwise excellent. The A* 300/4
has no issues on digital, excellent for digital
and is really small, great for handheld usage.

I agree, although I'd shift the comparison timeframe a little earlier. The MX
was small, fully-featured for what it claimed to be, and pretty successful.
It was also aimed at the low end of the pro market (and had a 5ps drive :-)

Interestingly enough the competition then for that style of camera was also
Olympus, with their OM-1.

  High-speed flash sync probably works fine for that, though.
 
 Does that produce multiple (or different in some other way) catchlights?

Probably, if you look extremely closely.

But if I'm using shutter speeds around 1/250s I'm doing that to blur
the wheels, and I'm panning with the car to try and prevent blur on
the body. The angle between me and the car doesn't change very much,
so the catchlight stays in the same place, both on the car and on
the sensor.
