I have a couple lenses that don't have an internal focusing system, and whenever I want to put them back in my bag, I turn the focus ring to make the lens shorter.
I noticed that when the lens is set to auto focus, the focus ring is harder to move than when it is on manual focus. Can I damage the focusing system by turning the focus ring when the lens is set to auto focus?
I would think that if the lens is off the camera it wouldn't cause any damage. Am I right?
