Tokina AT-X FISHEYE 10-17mm F3.5-4.5 DX for Nikon, offered for export. The exterior has no noticeable scratches and is in beautiful condition. There is no mold or cloudiness inside the lens, and nothing that would affect shooting. This is an APS-C lens, but it was sold by Tokina as an overseas model (for export) that can be used on full-frame cameras without vignetting. When used on a full-frame camera, it is 10mm, so it won't be a circular fisheye, but you can shoot with the top and bottom cut off. I don't have a full-frame camera, so please search the internet for sample images. Included accessories: original box, front and rear lens caps Size... Nikon F mount Focal length (wide angle)... ~10mm Focal length (telephoto)... ~18mm Open F value... 2.9~4
