중고 Nikon TC-17E II 1.7X 텔레컨버터

The 1.7x reach is exactly what I needed for wildlife shots on my F-mount lens, and the glass is still tack sharp even wide open. It arrived in clean condition with no dust or scratches, just as described.

Put this on my 70-200mm and the image quality is still sharp even at the long end, plus it locks on tight with no wobble. For a used piece of glass, the optics are impressively clean and it worked perfectly right out of the box.

I was skeptical buying a used teleconverter, but this one pairs perfectly with my 70-200mm and gives me sharp wildlife shots at 1.7x magnification without any noticeable loss in clarity.
