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.
