The AF DX Fisheye-Nikkor 10.5mm f/2.8G 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.^[2] 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-lens mount 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).
