As some of you may have seen I recently mounted a polaroid back on an old plate camera http://www.apug.org/forums/forum147/...te-camera.html, the contraption works fine, but I've since added a new lens mount so I have tilt/swing movement.
The mechanism works great, but I've encountered a new problem (one I'm sure most here will have already guessed) - just as I start to get some worthwhile blur there starts to be some vignetting and swung further I lose image area.
so, the problem seems to be one of coverage. The lens is an old IBSOR DRB 105mm shooting on 7.5cm x 9.5cm instant film. the lens covers fine straight on and covers the rise and shift fine.
my question is, how do I best solve this problem - do I need a wider lens or just a lens with a bigger diameter?
thanks for any suggestions
