Jerry,
You have made a *wise* decision.
But you could have used a more simple approach and just have a look at the camera real life results....
I have a K-7 and a K-5 and work with them side by side.
Still the K-7 is a wonderfull camera.
There has been a lot of critisism all around the K-7, especially on its noise production and its dynamic range.
Before the K-7 I had a K10D, sold it.
I can still remember the exitement people had for the resolution and the low light performance of the K20D.
Somehow people expected the same sort of step up between the K20D and the K-7.
Lack of IQ improvement does not mean that the K-7 IQ is bad in the first place.
In terms of noise and DR that did not happen.
All the more did it happen on the system upgrade with the K-7 body!
After one gets used to the ergonomics, it is *great*.
There was no other camera close in that class with all the features and functions packed into that machine.
Still my K-5 has not been able to make as beautifull shots as my K-7, also because I've not been in the position to do so, but still...
You must learn to understand the characteristics of the K-7.
For instance, the amount of visible noise is hardly noticeable in case of dark pictures with bright subjects.
When those pictures are then touched up in post processing, it can look impressive.
Let me show you what I mean.
This bush baby picture was taken hand held (SR on) with a DA*60-250mm and a K-7.
I could hardly see the primate with my own eyes, it was attracted with a piece of banana on a rod with a very small red LED lamp.
ISO 6400, focus 153mm, f 4.0, s 1/13 sec:
Not bad, huh? However, I did use NR in PP here.
Or this one, same camera & lens.
ISO 3200, 250mm, f4.5, 225mm:
ISO 1600, focus 250mm, f 4.0, 1/50 sec. NO noise reduction (I shoot 100% RAW):
Noise? I think it is more than acceptable.
Like this one again (ISO 1600, no PP):
This one taken with a DA* 16-50mm @ 50mm, ISO 1600, no PP:
Same lens and camera, now ISO 800:
And one more on ISO 1600:
Ok, it is not the ISO 6400 or even ISO 128000 that I sometimes use on the K-5, but well, when do you *really* need that?
Congrats again and have fun with these great camera's you've bought!
