[Leica] RE; Autofocusing M lenses

[lrzeitlin at aol.com]

About 40 years ago, give or take a decade, a precision camera make, probably Zeiss. marketed a camera in which the focus was adjusted by moving the film plane. This simplified lenses but had the downsides of increased expense for the camera body and the difficulty of providing enough motion for long focus lenses. The idea was abandoned after a few years but I believe that with modern electronics it could provide automatic focus for M lenses. But, of course, there would be little incentive for Leica to adopt such a system. Maybe a third party could sell a universal camera which would autofocus with all makers lenses.

Any idea whether this would actually work or not?
