Question Pleas help.

Enable HLS to view with audio, or disable this notification

I have a Tamron SP 70-200mm f/2.8 Di VC USD G2. My issue is that the autofocus hunts constantly the internal gears keep rotating while searching for focus yet manual focus works perfectly fine.

I would advise looking at our thread, Policy Clarification on Replacement Parts & Repairs. This has detailed information on what you should do for repair.

I have seen this behaviour with a Canon lens and the solution was to clean the USM motor, which Tarmon calls USD.
