Is this working with any Canon DSLR?

And with other DSLRs?

Can anyone confirm if it is working in your camera unit and post with indication of model, please?

Thank you.

Works on my 60D but it takes forever to focus. In the meantime I could have punched in and found focus manually more quickly. But that could be useful in cases where you can't see all that well.
