he put some comments up for the 70-200 for fx.
On the D3, however, issues occur with this lens. A certain amount of vignetting when the lens is set wide open is both to be expected and indeed readily visible. But stopping down one or two clicks resolves that issue nicely. The centre sharpness is excellent even on the D3, but the tendency for the corners lacking critical sharpness when the lens is focused towards infinity at its longer end is unexpected and troublesome. For landscapes at 200 mm, you need to stop down way too far to get the corners just barely acceptable, even to f/22 in some cases. I think the covering power of this slim design simply is not adequate for a good performance across the entire FX frame, at least towards the 200 mm setting. For PJ-style work or for studio and portraiture, this flaw is tolerable, but not for landscapes. Nikon really needs to come up with a Mk.II model of this general-purpose zoom lens.
