Any one know of a web site where I could go to check rather a certain brand lens is compatible with a certain brand of camera? I've looked but haven't found one that deals with len's other than nikon len's and nikon camera.

Maybe this can help http://www.photozone.de/Reviews/overview

thanks Vonkara...I'll check it out. Just to much used cheep stuff on e-bay and want to make sure what I get works on my camera. Gotta find a micro lens. Thanks again
