I got this week-end in a flea market two 135mm really cheaply. The first found was a Canon FD 135mm f3.5(II) and the other a Carl Zeiss Jena Sonnar 135mm f3.5 (Zebra) in M42 mount. Mounting the CZ is fairly straight forward, but I cannot say the same for the FD. So, my question is should I bother trying to fit the 135 FD or resale it ?
While having the FD opened for cleaning, I realized that machining an adapter would not be too complicated. However, I just wonder if it worth the time pass in the machine shop. Should I go out shooting with the CZ instead ?
