Nope. No focus by wire. It's old school, at least as old school as an
auto focus lens can be. To override auto focus you must disengage the
lens from the screw drive by switching off AF on the body. The one I
have is older and a bit beat up, the gears no longer mesh quite
perfectly so there's a slight whirring sound during manual focusing. It
doesn't bother me since I don't shoot video, but it is noticeable, and
probably happens to all copies as they age.
So if the lens is not attached to a camera body, if you turn the focus
ring, does the lens focus?
Yes, just like an old fashioned manual focus lens. It's nicely damped
for an early design auto focus lens as well.
