Here’s our concise review of the Nikon 20mm f/1.8 AF-S Nikkor ED wide-angle prime lens…
Nikon’s wide aperture 20mm has been a staple at PP towers, for good reason. It’s field-of-view verges on ultra-wide, while a maximum aperture of f/1.8 makes it ideal for astro.
The build quality is solid, with a mainly tough plastic construction housing 13 elements in 11 groups, including aspherical and ED (Extra-Low Dispersion) elements, which cut down on chromatic aberration and distortions. It also includes a Nano Crystal Coating, which helps to ensure that all imperfections are kept to a barely noticeable minimum.
The sharpness of this lens is excellent from f/4, though it can look a bit soft in the edges wide- open, which won’t put off landscape shooters who will find the sweet spot to be thoroughly rewarding.
The SWM (Silent Wave Motor) does a great job of suppressing any focusing sound, while the AF is both rapid and accurate. One small gripe is the lack of official weather sealing, though don’t let that put you off this absolute gem.
