Mount Nikon F mount
Focal length 20 mm
Max aperture f/1.8
Stabilisation No
Weight 355 g What reviewers say Both appreciate its compact build, bright aperture and strong central sharpness, but recommend stopping down for clearer edges and landscapes. Photography Blog praises low distortion and controlled colour fringing while noting corner shading. Camera Labs finds autofocus reliable and quiet, but sees wide-aperture background colour halos and softer distant corners. Both find it useful for low-light wide-angle work with those optical limitations.
