The title says AF. The description says manual focus. Then you say that all Canon AF lenses were FD mount, even though you described this FD lens as being manual focus. I don't understand at all.
Very few Canon FD lenses were AF lenses. The statement that all Canon AF lenses had an FD mount could not be farther from the truth. It is an EF mount that almost all Canon AF lenses have.
This all makes no sense at all, unless you are using "AF" to mean something other than "autofocus." If so, what do you mean by "AF?"
