[QUOTE="crycocyon, post: 133533, member: 13076"] So consider that from what I read it isn't a problem with the D700 because the pixel count is a lot lower. So the problem, at least from my cursory reading, lies with the size and the pixel density of the D800 sensor (and apparently of the D600 sensor as well from preliminary reports). Also consider that the same problem exists when I put the D800 in DX mode, although that is just a crop so I guess it wouldn't make a difference since the sensor still sees the same thing. It may have to do with how the light falls on the sensor and for an FX sensor of higher pixel density, there may be fewer differences in focal change at the pixel level than for a D700 which has much larger pixels. I'd have to look into that further. I can try a more systematic and careful focus correction, putting the camera on a tripod and using a static subject. But I've read that people have tried a lot of correction and it still shows up. But I agree.....why would f/2.5 be a problem even? I would expect perhaps f/1.4, f/1.8. And then why doesn't it show up with the 85 mm f/1.8? Anyone with a D800 and that lens? [/QUOTE]
