Used Nikon TC-201 2x Teleconverter

Swapped the rear cap immediately with one of my own, but the glass itself is spotless and the mount feels tight. Pairs nicely with my 300mm f/4 for extra reach without any noticeable rattling.

Put this on my D750 and the autofocus is noticeably snappier than my old teleconverter. The body cap and rear cap are a nice bonus since I always seem to lose those.

I was pleasantly surprised by the condition of this used teleconverter—the glass is spotless and it pairs perfectly with my 70-200mm lens. The included body cap and rear cap were a nice bonus, and it arrived well-packed. Definitely feels like a solid purchase for the price.
