AF lenses need to be designed with more play in the mechanism to allow them
to autofocus quickly. This is why Leica and Contax don't make AF lenses
(not SLR ones anyways). Lenses with play in them are "contrary to their
philosophy... blah blah blah". A consequence of this is that when the
lubricants stiffen up at low temperatures the AF lenses don't get as stiff.
