I have a Canon EOS film body and use a Tamron 28-300mm AF lens and a Sigma 100-300mm lens in Canon EOS/EF mount. I’m considering moving to a Canon EOS 600D DSLR and want to know whether these older third-party film-era lenses will be compatible and usable on the 600D.

There is no way of knowing. You would have to try out the lens on a DSLR to be sure.

Many of these older film era lenses from 3rd party manufacturers like Sigma and Tamron had compatibility issues with newer Canon DSLR's. Very often they would work fine wide open but as soon as you stopped down the lens aperture, the camera would lock up and produce an error message.

Some of these lenses could be "re-chipped" to make them compatible but they have been out of production for so long now, I doubt it is still possible.

They may fit and work, but compatibility is not guaranteed.

Because these lenses are Canon EOS/EF mount, they should be mechanically compatible with the 600D. The main uncertainty is electronic compatibility: some older third-party Sigma and Tamron lenses from the film era can have problems on newer Canon DSLRs. A common issue is that they seem to work wide open, but when the camera stops the lens down, the body may lock up or show an error.

So the practical answer is: you need to try them on a DSLR to be sure.

A few older Sigma lenses were sometimes “re-chipped” or had ROM updates for newer bodies, though availability for very old models may be limited. Tamron support for that is less likely.

Also remember the 600D uses an APS-C sensor, so the field of view will be narrower than on 35mm film. Your lenses will appear more “zoomed in” than they did on your EOS film camera.

In short: likely mountable, possibly usable, but test before relying on them.
