Thank you for viewing. This is the Nikon Z TELECONVERTER TC-2.0x. I purchased it new at a camera store last year to use at an event at the New National Stadium, where it performed well. However, I haven't had a chance to use it since, and I don't anticipate needing it for a while, so I'm putting it up for sale. I have confirmed that it works properly. The items included are shown in the fifth photo, and although not pictured, the included cloth bag is also included. The original box has a cut, as shown in the sixth photo. Please understand that this is a used item. Thank you for your understanding.
