Nikon AF-S Nikkor 20mm f/1.8G ED review – Our verdict
Fixed-focal-length lenses seem to be flavour of the month right now, particularly with photographers looking for the best-quality optics to match the latest generation of high-resolution sensors. As such, the AF-S Nikkor 20mm f/1.8G ED should prove to be extremely popular.
In terms of resolution, the lens is excellent, particularly at f/5.6-f/8, with only the very corners of the image showing a slight blur. There is minimal curvilinear distortion given the focal length of the lens, and the vignetting and chromatic aberration aren’t pronounced enough to be an issue. Besides, many of these issues are solved in-camera if you shoot JPEG images.
Those with Nikon DX cameras will be getting a fantastic 35mm (equivalent) f/1.8 lens, which will suit landscape and street photography. However, what I liked the most was the large aperture, as it really allows for some interesting shallow depth of field compositions.
