Adam:
So, I have been neglecting my K7 as of late because of know "noise" issues since I do a lot of bird photo and I do need high ISO settings a lot of times. I found the K20D better for that and maybe it's time to really test the K7 under those circumstances.
I always shoot RAW, so following your starting post presentation, I have shot a few pics in JPEG, using your own settings, i.e.: NR set at minimum ISO400 and NR at "Strong". Shots were taken at ISO 1600, 2000, 2500 and 3200. Lens used: DA*16-50 at f2.8, 4, and 5.6. Made sure to not underexpose either.
I have yet to upload the pics to the computer (I will), however, but from what I can see from the rear K7 screen in review mode, there might be a bit of difference between shooting RAW vs. JPEG with those settings, JPGE's being somewhat less "noisy" ... but not by a great deal.
Maybe it's me and I haven't quite adjusted all of the required settings properly for JPEG shooting? Is there anything else I should tweak?
I just cannot achieve the same photo quality as yours from what I see in your sample shots.
On the other hand, I admit having been a little rough in evaluating the high ISO capabilities of the K7, even in RAW, and I will return on a "field trip" this weekend, remount the DA*300/4 on the K7 and go with that.
One thing I do remember though, and that was part of the reason(s) why I switched back to the K20D for birding, is that even at ISO400, under a blue, clear sky, I could see some noise ... when I cropped the resulting pics at 50% and more though.
I am glad you took the time and the effort to show us what suddenly seems to like a revelation!
Cheers!
