Zhongyi Optics Lens Turbo II Focal Reducer Mount Adapter C/Y-NEX (Contax/Yashica mount lens → Sony NEX/α.E mount) ★Time Sale★ 17,000 yen → 15,900 yen I bought this because I wanted to use old lenses with my a6300. I've used it about a few dozen times. It has been stored in a dehumidified storage box. The original box, lens cap, and instruction manual are included. Thank you.
