A 58mm tube is used instead of a 42mm tube which I previously acquired, to avoid any vignetting. A M42 to EOS EF ring with electronic focus confirm is used, it is glued together to ensure proper orientation of the tripod socket.

Final form of the converted Canon FD 300mm 2.8 in EOS EF mount
This is the adapter used. It consists of a 77-58mm step down ring, and then a 58mm focusing tube, plus a 58-42mm step down ring. The flange distance is then adjustable to suit different situations.
