二手 Nikon TC-14E AF-I 增距鏡

I was pleasantly surprised at how solid this teleconverter feels—the metal mount is reassuringly sturdy compared to plastic ones I've used before. Paired with my 300mm f/4, it snaps into focus quickly and adds just the right reach for bird shots. A great used find that feels like new.

Got this for my old film body and the aperture coupling works flawlessly, no adapter fiddling needed. The glass is clean and sharp wide open, which surprised me for a used unit.

Mount this on a 300mm f/4 and you effectively get a 420mm f/5.6 that still autofocuses fine in decent light. The glass is clean and the mount feels solid for a used piece.
