Nikon Super Wide Angle 20mm f/2.8 AF Autofocus Lens

Nikon Super Wide Angle 20mm f/2.8 AF Autofocus Lens
Compact Full-Frame Ultra-Wide Prime – 94° Field of View, Close-Range Correction (CRC) & Lightweight Metal-Bayonet Build

The Nikon AF NIKKOR 20mm f/2.8 is a classic, ultra-compact prime lens designed for full-frame FX-format and DX-format Nikon F-mount cameras. Delivering a dramatic 94° angle of view, this lens is an exceptional tool for landscape, architecture, interior, and environmental photography. Its bright f/2.8 maximum aperture provides strong performance in low-light conditions and allows for effective separation between foreground subjects and background elements.

Optically, the lens features Nikon’s Close-Range Correction (CRC) system, which adjusts lens element groups independently during focusing to maintain exceptional sharpness, high contrast, and minimal distortion down to its 10-inch minimum focusing distance. Multilayer Super Integrated Coating (SIC) is applied to all optical elements to reduce ghosting and flare while preserving natural color accuracy. The compact, lightweight design features a durable metal lens mount and a physical aperture control ring for full compatibility with legacy film bodies as well as modern digital SLRs.
