John, it's not just the absence of the first and second cams. The flange is
slightly different and a ROM lens can only be mounted on an R3 or newer
body. The reason is that the ROM contacts occupy the space whee the first
cam was. If a ROM lens were mounted on an SL2 or Leicaflex Standard, the
ROM comtacts would be damaged by the body's cam follower. I recently
upgraded my 80-200 f/4 from ROM to 3-cam (yes I consider this an upgrade).
It now works perfectly on everything from the Leicaflex Standard to the R8.
