The mountain is 10 to 11 miles away with the foothills in the full-size image maybe a mile-and-a-half closer. Looking at the D3x and D7000 originals top to bottom in Photoshop at 100%, I don't see an appreciable difference in sharpness. The uploaded FX images show about 20% of the originals width and the DX about 30%.
I took four images with each camera, handheld, two with VR off and two with VR on. The differences in quality within each set were minor compared to the differences in quality that I see between the D3x and D700 images versus the D7000 images.
Should I expect greater sharpness handheld with the D3x and D700 with such distant objects? With the relatively low contrast and smaller lens openings, could this push the autofocus of the D7000 a bit beyond it's capabilities?
