Here are links to Web Sites that I have found of value with respect to the Topcon RE Super/Super D camera system. There are not many, but I will add new sites as I run across them.

http://www.marcoant.com   The Home Page of Marco Antonetto, the author of the book Topcon Story. This is the place to go to order the book.

http://www.pacificrimcamera.com  A good place to buy Topcon stuff. They are knowledgeable and helpful. They also have a section devoted to information about camera systems that is useful to the collector. Alas, nothing yet on Topcon.

http://www.ritzcam.com  Sandy Ritz is a good man to do business with and his online catalog includes a reasonable inventory of Topcon items.

http://topcon.8m.com 'Offical' repair shop for Topcon camera equipment. Also some cameras, lenses and accessories for sale.

http://www003.upp.so-net.ne.jp/Topconclub/   The Topcon Club site, published by Takomori Yoshida. This site is worth visiting, it has images of many rare Topcon items and some interesting information. Mostly in the Japanese language but now with expanded English text

http://cameraquest.com  A site published by Stephen Gandy. It is mostly devoted the better known brands, Nikon, Lieca, etc., but does contain some nice words about Topcon.
