Nikon 20mm f/1.8G ED Specification: Faster aperture and extra glass for improved optical performance

Updated from the original Nikkor 20mm f/2.8D wide-angle prime launched around 20 years ago, the new f/1.8G ED version offers an extra stop of light together with additional lens elements to improve image quality. The optical construction now sees 13 elements arranged in 11 groups including two ED (Extra-low Dispersion) and two AS (Aspherical) lens elements. The ED glass elements help improve contrast, as well as minimising ghosting, flare or chromatic abberation whilst the AS elements are designed to help control distortion at such a wide-angle focal length. The new fast f/1.8 aperture will be welcomed by photographers shooting in low-light, or after creative shallow depth-of-field effects with smooth bokeh. Nikon’s Silent Wave Motor (SWM) autofocus motor offers quick and quiet autofocus performance and the new Nikon 20mm f/1.8G ED lens is also compatible with Nikon APS-C cameras where it offers an equivalent focal length of 30mm

 

The new Nikon 20mm f/1.8G will be available from 25th September priced at $809
