IMO the K-1 was just only a code name.
They may want or not to reuse a code name as an actual  product name.

As I thought. But I do like the idea of a in camera lens database for
EXIF purposes.

Dave,

It's essentially the same setup as the SR lens length input, just with
quick access stored items and max aperture. Quicker than the Pentax
setup, but similar.

Oh, and I should note that all this enables is matrix metering, EXIF
data and accurate metering display data. Otherwise you still get
metering and aperture display is by delta rather than absolute(It
shows how many stops you've stopped down rather than the actual
aperture).

Seeing as there isn't any communication between the lens & body I 
reckon that system sounds quite good.

I'll even go so far as to say it'd be nice to see that system 
implemented by Pentax.

(it'll never happen, but it would be desirable for those with a lot 
of K, M & A glass)

Nikon does lens data WAY better than Leica. Database in the camera,
enter your lens data, press a button and twirl a wheel to pick the
lens, no mod to the lens necessary. Of course, Nikon's only using this
for EXIF and matrix metering, while Leica's got certain image
optimizations also applied.

exchangable focusing screen, so that I can stick a split-image screen in it.
Viewfinder like the MX, or, even better, the LX.  Autofocus for those who

Paul,
You really want me to go totally broke? I am trying to surmount the 
temptation, but you make it very hard :D Couldn't you just post images 
to show something bad about the K20D to save me from running dangerously 
low on money? :D

All the pictures are very impressive. As I read on a german page at the 
Photokina there will be 2 announcements from Pentax... a 'one numbered' 
and a 'three numbered' digital. If Pentax manages to make this sensor 
with Full Frame and releases a K2D with the same pricing policy (so 
cheaper than Nikon's D3 and Canon's 1D series... maybe somewhere around 
Canon EOS 5D?) then I believe the two giants could have a very serious 
competitor. With all the support from Samsung Pentax has all the 
possibilities to take bigger and bigger piece from the market-pie. Also 
if the 'three numbered' digital is the long waited Pentax 645D... :D

Cheers,
Timber

Ps.: Luckily we (Hungary) don't have K20D yet and hopefully we won't 
have it in the next 2 months :D

Re: K20D long-lens, high ISO samples

[pnstenquist]

Hi Jack,
Yes, the noise is noticeable on number three. It's the result of underexposing 
to preserve the highlight detail. Number two is basically the same shot exposed 
at about meter reading, but the bright highlight on the front of the bird burns 
out. A function of the light. Deail looks pretty good, even at 100$; Of course 
a TC and lens isn't the optimum answer. The first two were off the tripod, BTW, 
so you wouldn't have to lift it:-).

Re: K20D long-lens, high ISO samples

Noise is a slight bit noticeable on #3. Don't know if I could lift this
combination, let alone shoot and adjust focus at the same time.
I did sort of expect slightly more detail, but with the 2X T/C the
inadvertent rapid scene movement would have been extremely difficult to
overcome even at the noted shutter speeds and SR on.

Re: K20D long-lens, high ISO samples

[pnstenquist]

Thanks Micah. Sorry to tempt you:-). I had to sell a bunch of stuff to come up 
with it. And if I had done my income tax return first, I might have had to 
pass. Good thing I didn't do that:-).

Paul:

That first photo is really terrific, and all of these experiences with  
the K20D is making life very difficult for me: I just cleared out most  
of my debt and the urge to buy the camera is, how shall we say,  
strong.  The only thing keeping me from buying one is the image of my  
wife killing me for doing it.

K20D long-lens, high ISO samples

[Paul Stenquist]

Went out to the nature center today to give the K20D a workout with  
my A400/5.6 and A2X-S converter. This combination wasn't really  
working with the K10D or the *istD. Because the wide open stop is  
f11, I had to go to at least ISO 800, even though I was working off  
the tripod. Too much noise. The same was true for handholding the  
A400/5.6 without the converter. One of the reasons I wanted the K20D  
was to be able to use this lens and lens/converter combo efficiently.  
Some preliminary samples follow. All were with High ISO noise  
reduction set to weak.

A4005.6 with AF540GFZ flash and Xtender, ISO 800, handheld:
http://photo.net/photodb/photo?photo_id=7013146
I like this one.

A4005.6 plus A2X-S converter with AF540GFZ flash and Xtender on  
tripod, ISO 1000, exposure at meter reading, f8 @ 1/200th:
http://photo.net/photodb/photo?photo_id=7013166&size=lg.

A4005.6 plus A2X-S converter with AF540GFZ flash and Xtender on  
tripod, ISO 1000, exposure at f8 @ 1/1250th (about 2 1/2 stops under,  
but flash is pumping up the exposure. I had to push the midrange  
brightness on this which increased the noise, but it's still  
acceptable, IMO:
http://photo.net/photodb/photo?photo_id=7013168&size=lg

In brief, due to reduced noise at high ISO, the new camera is giving  
me long-glass capability that I didn't have with any of the other  
Pentax digitals.
