The AF-S DX Zoom-Nikkor 12-24mm f/4G is a lens manufactured by Nikon for use on Nikon DX format digital SLR cameras. It provides an angle of view on a DX format camera similar to that of an 18-35mm lens on a 135 film format camera.

Introduction
Nikon announced the lens on 18 February 2003[2] as the first lens specifically designed for the Nikon DX format.[3]
This lens was replaced by the AF-S DX NIKKOR 10-24mm f/3.5–4.5G ED announced on April 14, 2009.[4]
Target market
At the time the lens was introduced, Nikon did not make a zoom lens which would provide an ultra-wide-angle view on a DX format camera. Due to the crop factor of the DX format, wide-angle zoom lenses such as the 18-35mm provided an angle of view equivalent to a 27-52.5mm lens; more typical of a normal zoom.
The purpose of the 12-24mm was to fill this gap in the ultra-wide- to wide-angle range[3] that would otherwise require users to purchase relatively expensive prime lenses such as the 13mm, 15mm and 18mm Nikkors.
