Can I use the lens of my Canon SLR camera on a Canon Digital SLR (the Canon D20)?
I would like to buy an SRL Digital camera, but I'm sure if I can just buy the body and re-use a lens I have with my regular nondigital Canon SLR.
The digital camera I want is the Canon D20.
THe lens I have is EF 28-135mm f/3.5-5.6

Thanks!
I found a D40 used in great condition for 5, so that's why I'm considering the D20 over the D30.
Thanks
Oops..I meant a D20 (not a D40)

The 30D would be a very good choice.
All Canon EF lenses are compatible with Canon’s Digital SLR cameras.
EF-S lenses are only compatible with their Digital SLR cameras, and not their 35mm film cameras.
http://www.usa.canon.com/consumer/controller?act=ModelFeaturesAct&fcategoryid=139&modelid=12929&pageno=6 says that the EOS 30D is compatible with all EF and EF-S lenses. Buy the 30D anyway, as it is about a year newer and the same money or less, according to:
