GrumpyTim | Vintage Lens Repair - Prinzflex (Chinon) 135mm f2.8 - Aperture Mechanism Strip Down - Retrotech @GrumpyTim | Uploaded 4 years ago | Updated 2 hours ago
Having shown this Prinzflex 135mm f2.8 (actually a Chinon lens re-badged as a Prinzflex) lens in a previous video where we repaired a fault with the focusing mechanism and tested the lenses performance, I had a request from a viewer who had the same lens that they'd taken apart for repair but they couldn't remember how the aperture mechanism went back together, so they asked if I could do another video showing the back of the lens and the aperture operating mechanism. In this video you'll see the back end of the lens taken apart and put back together and then a few test shots at the end.
