The new model was specifically designed to accept the older technology. In the case of Leica, they specifically designed the bayonet mount to be larger than the LTM version--just for the purpose of using an adaptor with older lenses. At that time, Leica controlled all aspects of the new model's design--they didn't have to outsource such items as sensor chips and software, including these to their needs. 2. The adapted technology isn't radically different from the older technology. In the case of LTM to bayonet lenses, only the lens mounts differed. The lenses themselves were the same effective focal lengths; the rangefinder mechanisms were similar (if a lot more convenient with the M camera's combined rf/vf mechanism), the film area was the same, and the cameras used the same bottom-loading, 35mm cartridge film. The further you stray from the older technology, the sillier the adaptation can appear. Most adapters remind me of a middle-aged lady in the junior sportwear department. Sure, honey, you do have the physical ability fit into that vinyl skirt, but.... Jim Shulman Bryn Mawr, PA PS. Oh, Rollei wasn't immune to the same treatment: anyone ever try to shoot 35mm film with Rolleikin-adapted Rolleiflex? That's a barrel of laughs.
