Auto Chinon 1:1.4 f=55mm sticky aperture blades

Описание к видео Auto Chinon 1:1.4 f=55mm sticky aperture blades

My old Auto Chinon 1:1.4 f=55mm has some really sticky aperture blades, there was A LOT of old sticky oil in the aperture assembly so the pictures taken with this lens, would have been way too overexposed.
It’s not that hard to repair, just remember to set small marks at some of the parts, Before fully disassemble the aperture assembly.

There should NOT be any oil in the aperture assembly because it has to run dry.

To recording this video I use my iPhone 📱 11 pro max, and the wireless microphone is:
