This used to be the home of the experimental Canon EOS Wiki. A Wiki is a user contributed collection of information, such as you can find at wikipedia.org.
Unfortunately, since anyone can edit or add articles, it became full of spam rather than information about Canon EOS cameras, lenses and speedlites! I simply didn't have the time to constantly police it and remove all the the inappropriate material which was being posted, so I have reluctantly had to close it down.
For information on the Canon EOS system prior to the mid-1990s, you can visit the Canon EOS FAQ Pages. I'm afraid the Canon EOS Wiki is a failed experiment in this case. It's an example of how a few bad apples can spoil the barrel. I may resurrect the idea again at some point but for now I'm afraid the Canon EOS Wiki is unavailable.
If I can make the pages available in a read-only form, I will do so.
If you are searching for information on a particular Canon EOS camera, lens, speedite or other accessory, please try the search engine. It indexes the site quite well and may find things which are difficult to discover using the menu system.
