These tutorials originally appeared on a now-defunct Japanese website. A German website dedicated to the

Minolta manual focus system had copied the pages and kept them online after the original Japanese site

closed up, but the tutorials were written in Japanese.

We’ve translated them into English and are posting them on the Learn Camera Repair website so that they’ll

be available to English-speaking users, and to keep them available if the German site ever goes dark. You can

see the original Japanese versions on the Minolta SR Site:
