Tested Canon Zoom 512 (last clockwork mechanical Canon Camera)

Description

It's working condition and tested, it's the earlier Canon's 512 and used the imported Swedish spring, later version of the 512 has a big problem for freeze the winding, but not this version.
This was the highest-end model, with a spring motor drive system, and it was intended as Canon’s symbol of movie camera technology. The goal was to apply 16mm-movie-camera technology in an 8mm movie camera. The fast f/1.2 lens was the first to apply Gauss for the relay lens based on the high-magnification and high-resolution lens of the Reflex Zoom 8-3 (marketed in 1962). This camera, with a variable shutter opening and spring mechanism enabling long time shooting, was called a “masterpiece” of movie cameras and was used for a long time by movie lovers, who wanted to produce high-quality movies.
After this model, Canon movie cameras were named according to their zooming ratio and f/ number.
