Wide-Angle Prime. Compatible with FX- and DX-sensor cameras, the Nikon 20mm f/1.8 provides a 94° angle of view on full-frame and 70° equivalent on crop-frame cameras.
Fast Aperture. At f/1.8, you’ll be able to shoot in low light as well as create subject-background separation.
Optics. Two aspherical and two ED elements minimizes chromatic aberrations, while the Nano Crystal Coating reduces sagittal flare. The internal Silent Wave Motor gives fast, silent autofocus performance for both still and video shooting, while the rear-focusing design keeps the physical size of the lens the same at all focus distances.
