I'm thinking of buying a Canon 10-22 mm lens to go on my EOS300D but have heard they don't work on full frame digital cameras. As I'm thinking of updating later onto a 5D is that information true? We are off to Egypt soon and I really don't want to be comprimised with my 24-105 if space is tight with some of the monuments. Any help or suggestions greatly appreciated,
