Mount Ring Canon
Mounting a lens FD on EOS mount. Do I have to calibrate approach?

I bought an old objective of Canon 50mm f/1.4 FD 7D me, and a ring mount to fit. The lens works, but only allows me to focus at one meter. I wonder if the increase in distance between the sensor and lens mount, because it is causing the focal length to be off. Is this case, or is the lens, in general, just off because it is old and has not been used in 25 years? How I can go about calibrating the lens as well? I would do without having to send off with the fee to get worked on and pay them a fortune. Many thanks!

No, and manually focusing the lens FD, no calibration is necessary. Unless you bought the Canon adapter with the conversion lens perspective on it, you will not be able to focus to infinity but
