Nikon AF-S Nikkor 20mm f/1.8G ED

Nikon F (DX/FX)

Review

The Nikon AF-S Nikkor 20mm f/1.8G ED is an outstanding addition to any Nikon F (DX) mount photographer's arsenal. This lens stands out in the wide-angle category, offering exceptional clarity and sharpness while maintaining a lightweight and compact design. Its fast f/1.8 aperture provides excellent low-light performance, making it a versatile option for various photographic situations, from landscape to street photography.

One of the most significant advantages of this lens is its optical performance. The lens uses Extra-low Dispersion (ED) glass elements that reduce chromatic aberration and enhance contrast. This leads to images that boast stunning detail, even when shooting wide open at f/1.8. Additionally, the Nano Crystal Coat helps minimize flare and ghosting, allowing for clearer images even in challenging lighting conditions.

The autofocus (AF) system is quiet and quick, thanks to the inclusion of a Silent Wave Motor (SWM). This is particularly beneficial for videographers who require discreet focusing during shooting. The lens features a rounded 7-blade diaphragm, which aids in achieving beautiful bokeh, adding an artistic quality to your images that is hard to ignore.

However, while the lens excels in many areas, it is not without its shortcomings. As it's designed for the DX format, the effective focal length comes to about 30mm, which might not satisfy all photographers looking for extreme wide-angle perspectives. Additionally, some users might notice distortion at the edges, particularly when shooting wide open. This can often be corrected in post-processing, but it's something to keep in mind for those looking for a quick, in-camera solution.
