I was given two lenses for Canon EF mount, and have no use for them.

If it can make you happy, and help APUG, I'll be happy too...

Canon EF 35-80 1:4-5.6. looks good, seems to be working on my EOS3. Manual focus by the front mount, not very convenient IMHO.

Vivitar 70-210 1:4.5-5.6 with hood. Two rings, one for focus, one for zooming. Seems to be working on my EOS3.

No waranty of course, I don't know what they actually deliver, these are clearly cheap lenses.
