As for leica lenses on movie cameras, Leica mad an M to C mount adapter. Is C mount only 16mm or is it used on 35mm as well.

The answers I got don't agree with the table mentioned above. Here is what Leica told me: M 27.35 mm R 47.15 mm. Can anybody say which is correct? Was it a typing mistake? My reason for asking Leica was to find out whether M or R lenses could be used with any available 35 mm reflex movie cameras. My conclusion - M, no (I knew that to begin with, but lived in hope of a miracle); R - a possibility. Does anybody have experience of getting R lenses mounted in Arri or Aaton mounts? There is a reasonable chance of the Aaton conversion working because the ffd is 40 mm. The Arri conversion is less likely because that ffd is 52 mm. I would like to try the 50 mm Summilux instead of those cheap and nasty Super-Speeds from the Z company. Oh to use the Noctilux (I do have an Angenieux 25 mm f0.95 for 16 mm work but it doesn't come close to the Noctilux). The answer might be to disassemble an extension tube to make an R-mount front for the camera. Thanks, Malcolm McCullough </excerpt>
