Old analogue lenses

[RaoulIsidro]

I know that my old lenses from my Canon film SLR will fit on my new digital SlR and yes they do work but being new to Digital SLR's and a rank amateur, how do I actually know if they are satisfactory/still good for the job. Should I get them looked at? Should I just practise and see? I don't know if my own judgement is good enough. My old Eos 630 was used with Canon EF 28-70 and Sigma 70-210. My current camera is Canon 50D. I was going to buy new lenses for a course I will be attending.

Any Canon EOS lens will work on the new Canon DSLR's.
The Canon lenses before the AF Autofocus era were called Canon FD manual focus lenses.
They are the lenses that will not fit on Canon EOS Cameras.
The transition to EOS from FD occured in 1988.
Canon did a major thing no other camera manufacturer have ever done before.
They totally abandoned their whole FD lens system.
The Canon FD lens system is an orphaned line.
Unlike Nikon who looked after it's lens system. The new Nikon D7000 will be able to use Nikon lenses as far back as 40 years ago, but that's another story for another time...
