hankg Posted May 9, 2007 Share #1 Â Posted May 9, 2007 Advertisement (gone after registration) A prototype finder that accounted for focus effect on focal length. From the WestLicht Photographica Auction: LOT 134 M Prototype Prototype M-camera with experimental finder by Robert Eckhardt. Complicated optical/mechanical design allowed not only parallax correction, but also correction of difference of focal length determined by focus. An enlarged space was needed to fit this finder into the M top plate, therefore the regular straight M2/M3-type rewind knob could not be kept. The camera already has a cranked rewind, similar to the later M4. Technically, the camera is an M2, but with automatic counter. Original Leitz documents of Patent applies from fall 1958 included, signed by Ernst and Ludwig Leitz, top plate without engravings and serial number, the unique camera in fine and working condition.

hankg Posted May 9, 2007 Author Share #3 Â Posted May 9, 2007 Probably an issue of cost, manufacturing difficulty, reliability or all the above. It would be great though if it was possible though. Link to post Share on other sites More sharing options...
