As stated. Will a [FONT=Verdana, Arial, Helvetica, sans-serif]Sigma Super-Wide[/FONT] II 24mm 2.8 Lense work ona 300D? It's no biggie if it isn't going to work since I'll throw it in the bag with the EOS film camera. I've heard talk of required upgrades, but not sure if this applies to a Mark II. Anyone have any idea?
