Hi--

The "back spacing" for 35mm lenses and lenses for 16mm

movie cameras (what the "C" mount is used for) is VERY

different, forcing only very close focusing with the C-mount

lenses mounted on 35mm cameras (with a very small image

area, also). Doing this can be useful for macro work, but

best optical performance is often had with the lens reversed,

which makes for more mounting difficulties, and short focal

length lenses may be impractical non-reversed since correct

focus may appear inside the lens barrel. It is also hard to find

C-->Nikon-mount, though the reverse does exist and is made

by Nikon (not useful for this). Why do you want to do this...?
