The new Nikon D7000 shows promise, but finding lenses that can deliver to a sensor with 4.7-micron photosites should prove an interesting challenge, certainly not something likely with most consumer zooms, which is what Nikon shows the camera with in its marketing; having 16 megapixels is a token specification if the lenses cannot deliver. The new 35/1.4G (below) might be just such at lens, at least stopped down to f/2.8. Worth understanding is that diffraction will limit performance to f/5.6 with per-pixel performance quickly degrading at f/8 and beyond. See Making Sharp Images for more on diffraction. Of course, the video capabilities of the D7000 might be its main attraction, given the dearth of 1080p video on Nikon DSLRs, and for video, the diffraction issue is a non-issue.
