Just bought a Pentax smc DFA 50mm f/2.8 Macro Lens via Amazon.
The Clamp switch disables AF when set to ON (as expected) but there is virtually no difference in focus ring friction between ON and OFF.
The focus ring friction feels about right to me for manual focus. However, there is a little bit of frictionless backlash (i.e. when rocking the focus ring).
Initial macro results I would describe as less than super-sharp.
Reading several posts, it looks like the friction varies from "almost none" to "cannot turn" for other samples of this lens.

Do you think I've been sold a donkey?
