I recently got the 70-200 f2.8 s lens for my Z7 and love it.
However, in some challenging lighting conditions, when I manually focus by turning the focus rings. I heard some sound, very weak clicking sounds from the barrel, not loud by definitely noticeable.
The auto focus is smooth and quiet. and turning the focus rings with the camera turned off is also fine.
Do any of you have the same experience? Wonder if I got a bad copy or something. It's not cheap lens after all.
Thank you very much!
