Hi I have a canon slr lens 28-200 from a 35mm slr camera. I want to buy a canon 350d and want to know if the lens will fit slr digital cameras...thanks
Should do.
If it is an EF, EF-S and/ or EOS lens then you are laughing.
Virtually all canon lenses fit newer digitals so you'll be alright i reckon.
As fo3nix points out you will lose a little bit at the widest angle due to what is called 1.6 crop factor so dont expect exactly the same results you had with your film camera.
Some of the Sigma lenses dont work with newer digital cameras but generally they do.
I wouldnt want to commit myself and i suggest the best thing to do is to go to your local camera shop and try it out on a 350D body just to make sure.
I'm afraid the best answer i can give is that "some do, some dont!".
