Measuring Seiko #0 Shutter Times in Bronica Lenses

Tutorial by Max Vettore showing how to build a simple shutter speed tester for the Seiko #0 shutter used in Bronica Zenzanon lenses. His tester actually would work for any leaf-shutter camera, not just the Bronica lenses he uses in the tutorial.

Max had a website with a large number of excellent Bronica repair tutorials, which we had a link to on our Resources page. Unfortunately, the site has disappeared; so we have put up some of his tutorials here that we had gotten before Max's site went down.
