Used Nikon TC-201 Teleconverter

The glass is perfectly clear with zero scratches, and it locks onto my lens with a satisfying click. It's an excellent value for the price, and the 100-day warranty gives me peace of mind. Definitely a solid upgrade for my telephoto reach.

Came with the original caps and the glass is spotless — exactly as described. Mounted it on my 300mm and the autofocus still locks on quickly. Feels like a solid piece of Nikon engineering from back when they built things to last.

Little heavier than I expected, but it locks onto my 70-200mm with zero play. Tack-sharp results even wide open, and the 100-day warranty gives peace of mind for a used piece. A solid value that earned its spot in my bag.
