Canon EOS lense interchangeable with digital?

[jesster]

I am looking into buying a digital Canon EOS for Mr. Jesster. He already has a Canon EOS SLR. He has plenty of lenses for that. Im just wondering can you use the lenses for both digital and slr?

I haven't a clue about cameras.

Any use?

Thanks Clubman, from my reading of that it looks like they are.

They are. The mounts and fittings are the same on both the SLR and digital EOS cameras.

An exception to this is the EF-S digital lenses which will not fit on film SLRs.

I can confirm that. I was able to use old lenses from a 15-year-old film EOS1000 on a new digital EOS350.

There's a white and a red marker on the mount. You match that with the same colour dot on the lense.

The autofocus is slower than with the newer lenses and I think there's some minor quirk to do with effective focal length, but it works well.

It's more than a minor quirk, there is an effective 1.6x multiplier of the focal length when fitting lenses to a DSLR body. This will mean that your ultra-wide 16mm film lens becomes a not quite so wide 26mm but you obviously gain from this on the longer telephoto lengths.
