Used Nikon TC-201 2x Teleconverter

Sharpness is surprisingly good with my 70-200mm, and the glass is spotless for a used unit. It came with both caps and the 100-day warranty, which made me feel a lot better about buying secondhand.

The included body and rear caps are a nice touch, and the 100-day warranty gives me peace of mind for a used piece of gear. I tested it with my 70-200mm and the autofocus still locks on quickly, even at 2x. Sharp enough for what I shoot, and it feels solid.

The glass is spotless and the mount feels solid, just like new. The included body and rear caps are a nice touch, and the 100-day warranty gives some peace of mind for a used lens. It’s a bit hefty, but that’s expected for a teleconverter.
