Nikon TC-17E II converter

Well-suited to use with fast prime and zoom lenses, this teleconverter delivers superior, high-resolution images even at maximum aperture. The optical design maximises the performance of a lens and minimises chromatic aberration that can originate from the teleconverter itself. The front and rear surfaces boast a fluorine coating to repel dirt and moisture, and the lens barrel offers professional-grade weather resistance.
