Used Nikon TC-201 2x Teleconverter

Glass is spotless and the mount feels solid right out of the box—no wobble or play at all. Slapped it on my 200mm with the body cap and rear cap both included, and focus is as sharp as I’d hoped for a used piece. 100-day warranty is a nice safety net, but honestly, it looks closer to new than excell

The 100-day warranty gave me peace of mind buying used, and the included body and rear caps mean it arrived ready to mount. Glass is clean and the autofocus still locks on quickly with my long lens.

Paired this with my 300mm f/4 and the autofocus is still snappy even at 2x, plus the contacts are clean so no signal issues. The body cap and rear cap it came with are a nice touch for storage.
