How do the three lenses score against each other? I am under the impression the MF<AF<AFD, from random photos on the internet, but I am certainly not certain...
All are exceptional as far as image quality goes. I believe the lenses are identical except for the AF and AFD functions. If you have a Rollei that will take any of the above lenses, the main difference is the manual-focus one will most likely be the most robust, having less complexity. And more serviceable for the same reason, plus the dire lack of parts and service for Rollei SLR gear here in the U.S. and maybe even Europe.
