But my educated guess is: The scanning backs no as single line CCD's can be made very dense, eg; Leica S1, better light, etc... Instant (non scanning) such as Phase 1, (can't remember the others) I suspect yes. Since you are using the center of the lens (small CCD) you are using the best part and the lens frequency would cause fringing, aliasing, etc., unless cut to a frequency lower than the lens. Even true with very large CCD's as they cannot be as dense as smaller CCD's. Jim At 05:43 PM 10/16/2001 -0400, Austin Franklin wrote: > > You will be able to buy Leica brand digital cameras.
