I just noticed that when i set the lense to manual focus that it sounds like the motor is still connected when I turn the focus ring. I checked my other lenses and none of them make a sound but this lense is making a sound. To better describe this sound it makes the same sound the lense would in auto mode when focusing. So is it off to the repair shop? It focuses just fine in auto, but i dont want to damge it any further if it is damaged.
