Used Nikon TC-201 2x Teleconverter

Tested it with my 200-500mm lens and the autofocus is still snappy, which surprised me. The included body cap and rear cap were a nice bonus, and it came clean with no scratches.

The rear cap and body cap were both included, which was a relief since I always lose those. The mount feels crisp and the glass checks out perfectly under a flashlight, so the 100-day warranty is just a bonus.

The glass is spotless and the mount feels solid, exactly as described. It locks onto my 300mm f/4 with a satisfying click, and the 100-day warranty gives me peace of mind for a used piece. Shipping was quick and the caps were all included, so I’m ready to shoot right away.
