>The alternative is to go with interchangable lens rangfinder designs, which would be the digital equivalent of the Leica M cameras. Unfortunately, rangefinder designs are somewhat limited in what focal lengths are usable becuase of limitations in viewfinders. A zoom rangefinder is certainly possible, they are done all the time, but focal lengths are still limited to around 200mm (on the 35mm format) before there are too many optical deficiencies introduced, and the rangefinder optic becomes too cumbersome. Also, with this sort of design, you are looking at entirely new lenses that will transmit focal length information to the camera so that it can adjust the rangefinder focal length to match.
