That depends I think. The reason is that both the mechanical aperture

Well, Leica went from the 39mm screw mount to the bayonette M mount on the RF's.
Though they produced both for about 10 years. The reflex mount has changed in
detail several times.

Hi Bill I'm far from well-versed in the two cam / three cam scenario,

This is true. Think of it as the Canon version of the DA mount.
The major difference is that with the DA mount, you can use it on a
film body, provided you don't mind a cropped negative.

George,
Yes, it's true, the 300D/Digital Rebel 18-55mm won't fit on any other
camera. The lens on the body in the showcase at work has a plastic ring
that prevents it from being mounted on a regular body. Without that
ring, its back lens element comes so far back that in a regular (film)
