Hi I would like to buy the Sigma 24mm f/2.8 AF Super Wide II for my EOS 300 aka REBEL 2000. I suspect, however, that there may be a lens chip compability problem and that the lens will not work on the camera body. It may work in all modes or in P or TV mode but not AV or manual or it may not work at all. I am not sure about it. Has anyone used this combination? Will it work or would I need to get an older eos body for it? Any help is very much appreciated!
