Rokkor M mount lens compatibility with other M mount cameras

[Reinvention]

Are the Rokker M mount lenses compatible with the rangefinder focusing linkage of the Zeiss Ikon ZM Rangerfider?

Thanks,

Robert

The head bartender here has some good Minolta CL / CLE and Rokkor information here on his Cameraquest site:
https://www.cameraquest.com/cle.htm

I don't own the Rokkor / Zeiss Ikon combination, so I don’t have firsthand experience, but I cannot recall anyone on this site reporting having issues. Both companies use the Leica M standard as far as I know.

The 40mm lens for the CL (not CLE) lenses had a more steeply sloped RF coupling cam than other M-series lenses. This wouldn't have made a difference on a perfectly-set-up camera, but a given amount of angular error would produce more focusing error with a CL lens than a regular lens. There was a lot of discussion of this back in the day, but most likely the forgiving DOF of a 40mm lens prevented it from being a real-world problem. I don’t remember if the 90mm cam was the same way or not.

The only MR lens which is somewhat worthy now is 40/2. 90 is nothing special, 28 is self-generator of spots.
I would skip entire MR line now. Not worth it on any other than Minolta cameras. IMO.

Thanks, all!

I have the CLE Rokkor 40mm and it works/fits perfectly on my Leica bodies.

Owning both the 28/2.8 and 90/4 I've had no issues with using the rokkor lenses with any of my M bodies (Even though my 90 is the made in Germany by leitz version)

I had all three M Rokkor lenses a few years ago and I never had any issues in using them on my Leica M cameras.

Thanks, everybody!

on my M6, the 40mm works fine, also, as opposed to the optically identical summicron40 the minolta vesion is multicoated
