To add to what Douglas has written... read the ads carefully, when you buy your adapter. Mine works fine, on the 30d, and is said to run on the XTi/400d just fine. It should. However, when buying the camera we tried to put the adapter on the Canon 5D, and it would not go on! Apparently, my adapter is the EF-S mount, and will fit/work with any Canon using the smaller sensors (EF-S mount). It will now work or fit on any of the film or full frame (EF-mount) bodies. Obviously, however, Douglas has one with the EF mount, which will go on all the bodies! Moreover, on the 30D mine does activate the "beep"... so it is possible that Douglas' 300D and EOS 500 do not have a "beep", or that it needs to be turned on, via the menu. (I had to turn on the "beep" on the 30d menu.. o/w only the focus light (in the finder) would come on. Further thoughts... Focus Confirmation works with my: 21/4 SA 50/2 90/2 80~200/4 Vario 80~200/4 Vario with 2x converter ... though wide open (f8) it's getting a wee bit problematic for subjects in deep shade. 400/6.8 Telyt though it's a wee bit problematic for subjects in deep shade. FC does NOT work with the 400/6.8 Telyt and 2x converter - except very rarely, in brilliant sunshine. Even then, it usually will not work! Proof: The current Loon photo (See: http://www3.telus.net/~telyt/ and then click on "Featured Photo", on the left.) was focused with the help of FC, as the loon was in deep shade. Even with the f8 w/o aperture of the 80~200 Vario & 2x, the FC worked just fine. Certainly, if you look at the sharpness in the water droplets on the loons head, or the crispness of the iris in it's eye, you would have a hard time doing much better, by straight eyeball! My advice? Go for it! I bought a relative "cheapie" adapter, and I'm very happy with the results!
