Question about crop mode on the D3 and the D700

Depends on the camera and how you set the mode

I have a 12-24 DX

A) with auto crop off and D3 or D700 set to FX mode:

The entire FOV is usable/captured from 18-24mm (functions like a useful 18-24 mm lens on FF). From 12-18mm one sees the vignetting at the edges of the frame (like tunnel vision)

B) with D3 set to DX mode (either auto crop on or set to DX manually):

The area outside the DX frame goes to a dark gray through which you can still see the full FX FOV, but the vignetting from 12-18mm is much more difficult to see. All data is captured within the DX frame -- anything outside is of course, discarded.

C) with D700 set to DX mode (either auto crop on or set to DX manually):

The area outside the DX frame is still clearly visible but a dark black rectangle denotes the DX margins. You can still see the full FX FOV. All data is captured within the DX frame -- anything outside is of course, discarded. If you have grid lines on, these turn off when the camera is set to DX mode

D) with D3 set to 5:4 mode

The right and left sides of the frame are dark gray (just like in DX mode), but the full FX FOV is still visible in the viewfinder as described in (B). Everything in the area not grayed is captured; everything outside is not.
