  16-9.net   One very special resource, has a good collection of material about adapting both vintage and newer non-EF lenses to EOS mount (incl. Rangefinder lenses), as well as tons of comparisons in search for THE lens.   out of business
  MFlenses.com   Besides tons of reviews and other stuff they host the manual focus lens database dedicated to photos of the lenses themselves - BIG and unique (go to gallery > lenses)   no need to
 
  ACE   This is something different: a who-is-who database about manufacturers and distributors of photographic equipment. As to my understanding some of the information is not correct, but it's still a very interesting resource. Use at your own risk :).   (dead)
