p.1 #5 · p.1 #5 · C-mount to t-mount to eos, no correcting optics? | |
Some Cmounts, especially longer focal lengths, work with neglible vignetting on MFT. Others, mainly wide-angles, have a clear cutoff.
Adapters differ. For fast C-lenses, they need to acommodate optics that may be quite large, even at the mount-end. For the lens you wish to adapt, the outer diameter of the Cmount at the plane of the flange must be a bit less than the diameter of the MFT lens mount opening, while the lens itself can be thicker. Of the faster ones, the 50mm Schneider Xenon 0,95 performs well.
In the case of manually focussing some more specialized C-mounts, the electric contacts just inside the MFT mount have no function and may get in the way of the rear elements. No obvious solution in that case.
