Mark, I do not have your vast photographic experience, BUT the Epson RD1 is a really great camera and works well with my 35 and 50 summicrons. EVERYTHING of quality is expensive these days. Take a hard look at the RD1 as an option to keep your Leica glass alive I like my RD1 with these crons as much as I like using my D2x Jesse M. Kramer, M.D. Redding, California
