I have lenses from a Canon EOS-3 film camera and want to know if they will work on a Canon EOS 7D digital body. Are Canon film-era EOS lenses compatible, and are there any exceptions I should be aware of with older third-party lenses?

Yes, those older Canon film lenses will be fully compatible with a new Canon digital camera as they both use the same EOS system and EF lens mount.
Many older lenses from 3rd party companies like Sigma and Tamron may not be compatible as they were reverse engineered and can cause errors when used on the latest Canon cameras.

Generated from our catalog & community — verify before relying on it.
Yes—Canon EF lenses used on the EOS-3 are compatible with the Canon EOS 7D, since both are part of Canon’s EOS system and use the EF mount.
The main caveat is with some older third-party lenses (for example, certain Sigma or Tamron models). Some of those were reverse-engineered and may not communicate correctly with newer Canon digital bodies, which can cause errors or limited functionality.
So, if your lenses are genuine Canon EF lenses, they should work on the 7D. If they’re older third-party EOS-mount lenses, it’s worth checking compatibility for each specific model.
