Are Canon lenses compatible with other EF mount cameras?

[jimbe0]

I'm looking to buy my first pro camera but don't have the budget for a new lens. I have an amazing EF mount lens for my eos rebel t2i. I'm thinking of getting a black magic pocket but since the lens has a digitally controlled aperture I'm worried that if I use it on a different brand I won't be able to adjust the exposure without changing ISO or shutter speed.

Does anyone know if a canon ef lens would work on other cameras?

Nice catch, Rick.  I know for the other thread, there was no initial link in the signature.  Sneaky!  I'll keep an eye out for this new pattern.

This has been a constantly recurring problem for many years.
