Okay well I got a Canon 50e body from one of my mom's friends as a present because he wasn't using it but I'm trying to find a lens that fits it. I tried my friend's kit lens from his 300D but it didn't fit. I went to a camera shop and the guy recommended me a 50mm f/1.8 which was exactly the lens I was looking for. Went to a closer camera shop today and was told the same lens wouldn't fit. He said it'll only work on digital cameras but I also got the feeling he didn't know much about cameras. The lens was a Canon EF-S II I think. Anyone any advice?
