David/Chris,

You cannot mount ROM lenses on the SL2. It's physically impossible.
The mounts of the lenses have a raised section which has a slightly
larger diameter than the throat of the SL2 body. This prevents the
lens from seating flush with the bayonet ring on the camera body.
On the R8 (not sure about the other Rs) the bayonet ring has a step
machined out to accept the raised section on the ROM lens mount.

The SL2 uses twin cam lenses. The bottom cam operates the exposure meter
and the top cam the viewfinder aperture display. The lever actuated by the
top cam would hit the ROM contacts. If you were able to mount the lens on
the body there is every chance you would damage both the camera and ROM
contacts. It looks as if Leica saw the potential danger and found a simple
mechanical solution. If you try to attach a ROM lens to the SL2, even
though it won't fit you could still cause damage if you were persistent.

Bob.
