Canon 28mm lens and Epson R-D1
What with my passion being for pictures not equipment and my technical knowledge being limited, I'm hesitant to join this thread. However, as Moderator I think I should let readers know that my screw mount Canon 28mm lens (w/ Leica M-Mount adaptor) works perfectly well on my Epson R-D1. Also, 28mm is one of the R-D1's setting for frame lines within the view finder--indicating that the camera is designed to accept and perform well with both Leitz and Cossina Voigtlander 28mm lenses. I'll check on this. I also seem to recall that the Cossina Voigtlander 25mm lens works well on the R-D1.
In light of Tony Rose's $4995 price tag for the Leica digital M, the R-D1S's $2,000 price seems rather attractive for such a good digital rangefinder camera.
For a lengthy report on the Epson R-D1 after 18 months' use, see my article on the "Leica the Only Quality Compact Digital" thread.
The only difference between the Leica M's and the Epson R-D1 that I've perceived in over 18 months using the R-D1 is that although the R-D1 is modeled after the M series Leicas it doesn't have the latter's ruggedness and endurance. Using it as I used my M2s, M3s and M4s had required an adjustment of the way I handle it toward the tender side. Otherwise it's a great camera and performs beautifully with all old Leica lenses I've put on it.
More later when I can check technical details.
