I hadn't thought of that aspect. Good point. I was thinking of 48MP sensor exactly based on 12MP rather than higher=20 density. That would obviously need larger format lens as there is limit=20 to image size (i.e. 35mm lenses adapted to a 2" x 2" body will give=20 shading and distortion at edges of image), apart from fact your=20 "Standard" lens would be a different focal length for same field of view. The other way works (35mm format standard lens becomes telephoto on a=20 1/4" image sensor). --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
