Introduction

edit

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

edit

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.

Features

edit
  • 12-24mm focal length (approximately equivalent to an 18-35mm lens used on a 135 film format camera)
  • Compact silent-wave autofocus motor with full-time manual override
  • Nikon F-mount lens exclusively for use with Nikon DX format DSLRs
  • Extra-low Dispersion (ED) glass elements to reduce chromatic aberration
  • Aspherical elements to reduce distortion
  • Super integrated coating (SIC) to reduce flare and ghosts
  • Internal focusing (IF)[2]

Construction

edit
  • eleven lens elements in seven groups
  • three aspherical elements
  • two ED glass elements[1]
