Nikon AF-S 20mm f/1.8G ED
The long-awaited update to Nikon’s 20mm fixed wide-angle
Nikon produces a wide range of G-type zoom lenses using its ‘silent wave’ autofocus system, but many of the company’s fixed focal length lenses are older, D-type optics. These have aperture rings on the lens and rely on the older, noisier screw-drive autofocus system in the camera body – a feature no longer offered on D3000or D5000-series cameras. Although Nikon already has a 20mm f/2.8 D-type lens, this new 20mm f/1.8G ED brings both faster, quieter autofocus and more than a full stop of improvement to maximum aperture. The Nikon AF-S 20mm f/1.8G ED is a superwide-angle lens for full-frame (FX) cameras but, like all Nikon’s full-frame lenses, it can also be used on DX models, though the effective focal length becomes 30mm, so it will act like a mediumwide-angle lens rather than a super-wide.
