The two Nikon sampes here post1196215 and here post1196229 have a different cast and both look over exposed to me. Are they overexposed as they were shot or in PP? Latter would add noise... maybe D7000 isn't so bad.
These aren't Nikon images, they're K20D images:

Both images were shot in RAW with a K20D.
They were processed using ACR6.2 and Topaz Denoise(for NR).

The first image was part of some low light ISO6400 trials I conducting a few months back. I used the SMC-A 50mm 1.4 @ f/2 with a shutter of 1/10s

The second image was taken at ISO 1250 with a PK/A Vivitar 28mm 2.8 CF @ f/4 1/100s(to help isolate the subject against the background).

I think that one of the beauties of the K7 (and I suppose the K5) is the accurate white balance. Obviously if you shoot RAW you can fix that in post processing, but it cuts an amazing amount of time in post if the camera gets right in the beginning.

I don't know what to make of the second D7000 photo posted. It certainly doesn't look like the sort of place where I would be using high iso. could easily have shot that at iso 200 or 400 and had a decent shutter speed. At the same time, even in good light, the K7 at iso 6400 looks like crap, both with regard to dynamic range and noise.

That's true!
I hope I didn't confuse anyone with those

FTR. if those were taken with a K-5, I'd expect them to look every bit as good at ISO51200.

If representative, the K-5 high ISO performance is impressively better than the K-7's. Now let's see comparison of acuity and dynamic range at max IQ - low ISO, RAW, tripod mounted images through a sharp lens at optimum aperture.
Indeed.

Nice one! These lenses work very well at small distances and stopped down one, as you demonstrate. Sort of a sweet spot.

I think it says that it's shot in bright mode, though, that explains some of the high contrast.
Good catch - I hadn't noticed that. But that shouldn't be the reason for the lack of shadow details.
