AF-S DX Zoom-NIKKOR 12-24mm f/4G IF-ED

This ultra-wide-angle lens, designed exclusively for use with Nikon’s DX-format, provides a versatile wide-angle zoom perspective.

Key Features

Design enables a combination of wider angle-of-view with optical characteristics that are optimized for Nikon digital SLR camera sensors.
Nikon’s design produces a smaller image circle (the size of the image that is projected by the lens on to the sensor) enabling smaller lens diameter and optimal image quality from center-to-edge-to-corner on the image.
2 Extra-low Dispersion (ED) glass elements for minimized chromatic aberration.
Internal Focusing (IF) design for smoother focusing and great body balance.
Nikon D-type design provides precise distance information for flash and ambient light exposure processes.
DX Nikkor is designed exclusively for use with Nikon digital SLR models.
2x zoom ratio and variable angle-of-view from 99 degrees at 12mm to 61 degrees at 24mm, comparable to that of an 18-36mm lens on 35mm size sensor format.
Exclusive Silent Wave Motor (SWM) enables ultra-high-speed auto focusing with exceptional accuracy and powerful super-quiet operation.
3 aspherical lens elements for low distortion.
Manual/Auto mode enables instant switching from auto focus to manual with virtually no time lag even during AF servo operation.
Rounded diaphragm to make out-of-focus elements appear more natural.
11.8 close focusing distance throughout zoom range.
