Impossible? Perhaps not. A 55-200 4.0/5.6 GII VR kit lens (DX), on my D750 is just (well, almost) such a combination. With image area on 1.5 (DX) crop factor and field of view of 300mm there is no vignetting as expected. But on 1.2 crop factor, there still is no vignetting but with a slight darkening in the corners, and an effective FOV of 240mm. On FX, full frame, there is vignetting out to about 110mm. The rest of the way to 200mm is clear. Not bad for a kit lens IMHO!
Comments?
Is using a DX lens any different that using the crop tool in post processing? Not really. But the edges and corners of a DX lens will be less than crisp compared to a FX lens, even on a 1.2 crop.
