In this video I will show you how to clean the front and back lensgroup's lens elements in Canon FD 50mm 1:1.4 (New version)
I use both "ECLIPSE" and lighter fluid and "PECPAD" lens tissue to clean the lens element's.
Remember to set a small mark inside the lens on the aperture system so you are sure where the aperture assembly has to sit correct when assemble the lens again.
