There may be a difference in available aperture settings.
I have both and EF mount and Nikon mount.
EF mount is camera selectable in 1/3 stops.
2.5, 2.8, 3.3, 4, 4.8, 5.6, 6.7, 8, 9.5, 11, 13, 16, 19, 22
Nikon mount is lens selectable
2.5, 4, 4.8 5.6 6.7 8 9.5 11 16 22
There are no half click settings between 11 and 22 and 2.5 and 4. Between 2.5 and 4 you can get 2.8 by Av metering and carefully turning the aperature carefully until you see a time change.
The optics are the same with all 125s. I have shot with both on my Canon and see no difference in the images produced by either lens.
I confirmed with other Nikon mount lens owners about the no half clicks. I would assume that both Olympus and Minolta mounts would be the same.
Additional information stated in the Voigtlander 125 manual
M42 mount
Precautions for use of hood with M-42 mount
As M42 mount is of screw in mount type, distancce index or aperture index does not always stop at the right position. However, the photography is not affected even when a hood is obliquely set on the camera body.
Use with EF mount or Maxxum mount.
To use with EF by Canon and Maxxum mount by Minolta manual focusing is required. However, use of focus and function (focus display funcyion) is allowed, and auto exposure mechanism fully works.
Hope this info helps you.
