hi again, okay here is another matter i need some help with. what is the difference in the physical size of the D1 X's CCD and the normal 35mm negs?? I i know that the CCD is smaller and this effectively makes, say a 24mm lens into a 28 mm or so. but in what ratio exactly does this work?? and what lens do i need to use in order to get the kind of coverage i would normally get with a 24 or a 18mm??? looking forward to your help on these issues............ regards........ sumeet.
