Used Nikon TC-201 2x Teleconverter

The cap fit snugly and the glass is completely clean, just as pictured for an excellent+ item. I’ve already tested it on my 70-200mm and the autofocus is still snappy with the 2x reach.

Picked this up to pair with my 300mm f/4, and the autofocus still locks on fast even with the extra 2x reach. The mounting hardware feels solid, and the included caps were a nice bonus for storage.

The glass is spotless and the mount clicks on solidly, exactly as described. Body and rear caps included plus the 100-day warranty gives me peace of mind for a used lens. Shot a few frames at 2x and sharpness held up better than I expected.
