Nikon 16mm f2.8D AF Fisheye Nikkor lens mount_Pentax K The Sigma EX 12-24mm f4The Nikon 16mm f2. 8D AF Fisheye Nikkor is, as you may have guessed, a fisheye lens. It records a 170 degree image from corner to corner with all the circular distortion you'd expect from a fisheye. But it's a full frame fisheye, so it will produce an edge to edge image that takes full advantage of your sensor's resolution. In excellent condition, with very minor cosmetic wear; glass is clean and clear. Includes front and rear caps.
