Hmmm... With normal rotational pressure
(like from focus/zooming) there should
be no play - but with more force, there
should be (the pin that locks the lens
on should fit perfectly in the hole in the
camera bayonette face - but the lens locking
slot that engages the pin is usually wider
than the pin for reliable locking [also,
conceivably, if you do not hold the lens
release button in when puting on a lens,
the slot may get worn slightly wider {but
I don't think this is really a problem...}]).
If the bayonette springs (what actually hold
the lens in place) in the back side of the
camera bayonette are weak, or if there is
a lot of grease between the lens and camera
bayonette surfaces, there will be less
resistence to turning the lens. Also unlikely,
but the bayonette screws could be loose on
the body or lenses...
