Nikon AF NIKKOR 20mm f/2.8 Autofocus Lens Review

The Nikon AF NIKKOR 20mm f/2.8 is a compact ultra-wide-angle prime lens designed for Nikon F-mount cameras. At 20mm, it offers a classic wide field of view suitable for landscape, architecture, and environmental portraiture, while the f/2.8 aperture provides modest low-light capability and subject isolation. This particular unit is a used bargain-grade model sold through KEH, priced at $148 and including caps and a hood.

As an older autofocus design, this lens predates modern optical coatings and silent-wave motor technology, which means it may exhibit more flare and chromatic aberration compared to contemporary glass. Autofocus speed and accuracy will depend on the camera body in use. The 62mm filter thread is standard and convenient for accessory compatibility. For creators working with older Nikon DSLRs or those seeking an affordable entry into ultra-wide shooting, this lens delivers the focal length at a low cost, though expectations should be tempered by its age and the bargain condition grade.
