I'm selling this because I no longer use it. An aftermarket tripod collar (brand new) is included. Other accessories include the lens hood and front/rear lens caps. There are some scratches on the tripod collar ring. The optics, AF, etc. are all in good working order. Z mount. Nikon 70-200mm f/2.8 zoom lens, offering excellent descriptive power and brightness. - Brand: Nikon - Model Name: 70-200mm f/2.8 - Lens Type: Zoom Lens - Maximum Aperture: f/2.8 - Hood: Included - Lens Diameter: 77mm Thank you for looking.
