Just a DIY excercise to make this lens useable on several cameras I have.
Much more difficult than the 58mm lenses because there is no spacer ring.
Also, M42 T mounts and reversing rings are not wide enough and an intermediate ring must be turned to mate with the aperture ring.
Anyway some funny reversals;
The 58mm f/1.2 can also be converted relatively easily to the EOS mount.
