This apparatus - how else to describe it, I don't know - can be used in a Sinar M camera and presumably with Leica lenses. The quality of the images is astounding. I've been using the backs on a copy stand for numismatic photography in 16-shot mode which gives twice the resolution and twice the color depth, 8k x 11k pixels with 14-bit color. Stitching does take a bit of computer time. see http://www.sinar.ch John Nebel Marc Attinasi wrote: > Does anyone know if there have been attempts, by any manufacturer or > researcher, to use two or more chips to cover the 24 X 36 frame?
