Canon EF 50mm f/1.4 USM lens assembly (after repairing focus stuck problems)

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