Q:

Where is the serial number on a Tamron SP 150-600mm F/5-6.3 Di VC USD G2 (A022)?

On the first-gen (A011) model it was stamped faintly in the black plastic near the manufacturer location. I don't see it anywhere on the G2. I did receive a 1/8 sheet printout with the serial number on it. Thanks. 

A:

Well, shoot. It's stamped right on the zoom ring, in line with the focal length index, very tiny.
