Canon EF 24-70mm f/2.8 L USM repair hunting focus problem by cleaning the focus strip bar

This video is about repairing the Canon 24-70mm f/2.8 EF L USM lens which has focusing problems. The lens was hunting for focus on certain zoom settings, and it was caused by a dirty focus strip. So I had to remove the USM motor, disassemble it, clean the focus strip and then assemble the USM motor and the lens.
