I'd like to buy my teenage son a 35mm slr camera for Christmas. It's been\nyears since I looked at cameras. I've looked a bit online at stuff like the\nCanon EOS series. I want something that can be used in both auto and manual\nmode, and hopefully that's capable of upgrading in the future. What\nrecommendations does anyone have in the 0 range (body and lens(s)? Also,\nwill an old lens from an old Canon camera fit the new bodies? Thanks in\nadvance. Please email and remove the "nospam" in my address.
