Canon EF 50mm f/1.4 USM lens - repairing the focusing problem

This is a video about repairing the Canon EF 50mm f/1.4 USM lens which has focusing problems. I had a Canon EF 50mm f/1.4 USM lens which focus was stuck, and did not move. This problem was caused by the deformed metal ring inside the lens, and in this video I'll show you how to repair it. There are two other videos on my channel, which are about disassembling, and assembling the lens.
