EDIT: MODS Don't freak - I tried 10,000 different ways to post a LINK to this image and it didn't work, so all I can do is post the REMOTE image on here and ask you to change it to a link for me when you have time, thanks (in this case the resolution is important so I'd rather not resize it.. just post a link.)
All the hosted samples are ISO 100 and processed through Nikon Capture with the exception of the B&W image that's ISO 100 but out of the camera. They're not very telling. The photo of the young man in a beret has poor shadow noise, probably too much exposure compensation. The others are okay if uninspiring.
When opened with Capture these images at 200% are very close to D70 images at 100%. Dynamic range seems good in the nightime photo. Lots of range of illumination in that one, and few blown highlights or lost shadow detail. I'd like to see some NEF's, but based on these images I'm pretty happy.
