Any Zeiss focus errors with M10R?

Zeiss 35 f2 Biogon and 50 f2 Planar for use on an M10R. 

I have come across articles about them being calibrated for film rather than digital sensors so there would be front focus errors.  These were particularly relevant to the M9.

Does anyone know if this would be a problem with the M10R?

Thanks

Welcome to the Forum and we look forward to seeing some pics .

I think that is probably outdated opinion. That said, I think with the 35mm f2 you will struggle resolution wise and you will do better with f2.8 Biogon. 

Leica have just launched the 35mm APO for a reason. If you have an R surely the whole imaging chain has to be excellent, including our own techniques.

I had sent my camera and lens to get calibrated, I was seeing focus differences at 0.95 and 1.4 . I was not able to get infinity focus. This was on the M10-p

M10-r has be wonderful for now.

I don't know where you can send in the Zeiss lenses for that. Some older lenses had back focus issues, nothing on the newer generation, but it is a Lens problem and not the camera.

I have both the f2 Biogon & Planar. They are excellent on my M10.

Hi,

just to clarify, your M10r exhibits no focus shift with these lenses and no problem with infinity focus?

thanks

As far as I know these lenses exhibit no focus shift. (i.e. shifting of the focal plane when the aperture is stopped down). A camera cannot exhibit focus shift, as that is a lens property.
It is indeed true that older Zeiss lenses used a different  calibration than Leica did, but that  has not been the case for many years any more. If camera and lens are delivered properly set up, the combo should focus perfectly.

Usually it is not a problem with the camera anyway. it is an optical design problem if it backfocus, it is more visible in digital then Film.  and it is only an issue with older lenses made for film original 

The M10-R works great

Correct me if I am wrong but I think OP means to say focus error rather than focus shift.

Yes that’s correct! Apologies for not making that clear.
