Adapter Nikon F/G lenses to X1/2D

[doc steel]

Using Nikon F lenses on X system cameras cannot cover the 33x44mm sensor size   ......  (corners are severely vignetted even with big image circle lenses like centered tilt shift lenses).

This is definitely false and the opposite of your claim can be easily proven.

Agree..

I use the Fotodiox with the Nikon 85mm 1.4 and fills the frame. Very nice bokeh.
