Nikon AF-S NIKKOR 20mm f/1.8G ED camera lens

Ultra-wide 20mm FX prime lens

The Nikon AF-S NIKKOR 20mm f/1.8G ED is a compact, lightweight FX-format prime lens offering a 94-degree angle of view. Its fast f/1.8 maximum aperture provides strong low-light performance and shallow depth of field control. The Silent Wave Motor drives fast, accurate and near-quiet autofocus down to a minimum focus distance of 0.66 feet. Aspherical and ED glass elements with Nano Crystal Coat reduce sagittal flare and chromatic aberration across the frame.

Sustained optical quality at wide apertures

Stopped down or shot wide open at f/1.8, the lens maintains sharp rendering from centre to corners thanks to its advanced optical formula. The Nano Crystal Coat effectively suppresses ghosting and flare when pointing toward bright light sources during extended sessions. Internal focusing keeps the barrel length constant, preserving balance on a gimbal or tripod during long video takes or time-lapse sequences. Ultrasonic focus drive remains responsive without hunting, even in dim continuous shooting scenarios.

Upgrade from slower variable-aperture zooms

Photographers moving from f/3.5-5.6 kit zooms gain two full stops of light gathering and a fixed f/1.8 aperture across the focal length. Videographers using variable-aperture lenses eliminate exposure shift while zooming, though this prime requires physical repositioning instead. The 0.23x maximum reproduction ratio limits close-up work, so macro specialists should look elsewhere. On DX bodies the field of view narrows to a 30mm equivalent, changing the ultra-wide character.
