Digital Camera World Verdict

This Nikkor offers a wider viewing angle than a standard zoom lens, along with a faster f/1.8 aperture. It’s great for shooting everything from architectural interiors to expansive landscapes and cityscapes, and the night sky. Sharpness is mostly excellent, apart from at the edges of the frame when using very wide apertures and build quality is very good even though the lens is refreshingly compact and lightweight. It’s quite pricey to buy but good value nonetheless.

As an ultra-wide-angle fast prime, the Nikon AF-S 20mm f/1.8G ED is pretty compact and lightweight by current standards. Measuring 83x81mm and weighing 335g, it works well as a walkabout lens on FX (full-frame) cameras and is also worth considering as an ‘effective’ 30mm wide-angle prime on DX (APS-C) format bodies.
