Used Nikon TC-20E 2x Teleconverter

The front and rear caps were included as promised, and the glass looks pristine with zero scratches. I paired it with my 300mm f/4 and got sharp results even wide open, which I was honestly worried about with a used teleconverter. The 100-day warranty gives some peace of mind too.

Picked this up to extend my 70-200mm and it locks onto subjects just as fast as my bare lens. The included front and rear caps were a nice bonus, and the 100-day warranty gave me peace of mind for a used piece of gear.

The front and rear caps fit snugly, and the 100-day warranty gives me peace of mind on a used lens purchase. I've tested it on a couple of shoots already and it locks onto the camera body with zero wiggle. Exactly what I hoped for at this price.
