Vintage Lens Repair, and Test - Auto Chinon 200mm f3.5 - Cleaning the Optics

Описание: In this latest Vintage Lens Repair video we're taking a look at an Auto Chinon 200mm f3.5 M42 screw mount lens, made in Japan in the 1970s. The lens had been dropped at some time, damaging the integral lens hood and filter thread so those needed fixing. Also the glass elements needed cleaning - more because of dirt and grime than fungus in this case.

In the video we'll dismantle the necessary parts of the lens, fixing the various issues along the way, before testing the lens both for still images and seeing how it performs as a vintage lens for video.

The lens test section starts at 09:53
