I'm sure this may be seen as one more version of the perennial "What Should I Buy?" question, but maybe not:
I shoot manual focus film-based rangefinders. Less because I'm enamored of film and more because the cameras and lenses are small and light.
Manual focus is increasingly a problem for me, so I am looking at going to autofocus. With the exception of the Contax G2, autofocus cameras do not exist in rangefinder land.
So,is there a digital SLR that's about the same size as a rangefinder, with a selection of lenses, that I might consider? I also own a Canon XTI fitted with a battery grip. With its lenses, it's too cumbersome for me to haul around, to give you an idea of my requirements.
I know about the Leica 8 and the Epson RD-1 (too expensive and too much of a parts and repair risk, respectively.)
