Nikon F3 type D screen (in 35mm adapters)
 
Am I correct that type D screen has no frensel correction? So it will not function as any other SLR focussing screen and will still cause vignetting. http://www.mir.com.my/rb/photography...3ver2/screens/

As I have 55mm f1.2 lens I got no vignetting but f2.8 causes it already not to mention f4 ultra wide angle lens (EOS mount)...

Why there is no vignetting seen on usual 35mm photographic film but it is seen on my cam`s screen?

BTW: black negative (transparent) 35mm film makes great GG, exactly film look ;)...

Film has a much higher dynamic range then your camcorders cdd. The vignetting is there on film but its not as sensetive to it as i understand.
