The AF DX Fisheye-Nikkor 10.5mm G ED is a fisheye lens manufactured by Nikon for use on Nikon DX format digital SLR cameras. It provides a full 180-degree angle of view on a DX format camera.
Introduction
Nikon announced the lens on 22 July 2003. It was the first prime lens released by Nikon specifically designed for Nikon DX format DSLR cameras. The lens produces a distinctive rectangular fisheye image, which fills the DX format frame (as opposed to a circular fisheye lens which produces a circular image). The lens does not support autofocus on the D40, D40X, D60, D3000, and D5000 as it does not have a built-in focus motor.
Features
10.5mm focal length (approximately equivalent to a 16mm lens used on a 135 film format camera). Nikon F-mount lens exclusively for use with Nikon DX format DSLRs. Full 180-degree angle of view. Rectangular fisheye image.
Construction
10 elements in 7 groups. 1 ED (extra low dispersion) glass element. Built-in hood. Rear gelatin filter (no front filter thread).
