I just aquired a 24-105 from a dealer. It was second hand but is virtually new, having a UW07 date code.
It has just arrived and I was like an excited child opening the box.
Taken a few test shots. Happy with the results, but, I was suprised I could hear the IS motor. On my little old kit lens I could never hear anything.
My concern is; is there an issue with the motor? or is this normal?
My thoughts are I am being paranoid, but, thought I would ask for the thoughts of other owners of this lens.
