Sony FE 20mm f1.8 G Lens

The Sony FE 20mm f1.8 G Lens is a full frame, super wide angle lens for the Sony E-Mount cameras. It is a welcome addition to the Sony mirrorless lens lineup, incorporating some of the newest optical designs and technological advancements available, making it a strong performer for full frame and crop frame bodies alike.

Super Wide Angle Prime Lens

The FE 20mm f1.8 G is the widest prime lens available for the Sony full frame mirrorless bodies. The 20mm focal length achieves a 94° field of view on full frame bodies, and a 70° field of view on crop frame bodies. The dust- and moisture-sealed design means worry-free shooting in less than ideal conditions when out in the elements.

Bright f/1.8 Maximum Aperture

The FE 20mm f1.8 G has a maximum aperture of 1.8. This makes the 20mm the perfect lens for extreme low light photography, like astrophotography or other nighttime applications. The fast maximum aperture also allows for a shallow depth of field, and the rounded non-blade diaphragm ensures a smooth and pleasing bokeh, giving the lens a unique range of abilities not generally found in wide angle lenses.

Advanced Optical Design

Sony has included two Advanced Aspherical elements in the FE 20mm f1.8 G. These elements reduce distortion and spherical aberrations, resulting in razor sharp images. The inclusion of three extra-low dispersion elements also helps to reduce color fringing and chromatic aberrations for better clarity and color accuracy, with the elimination of purple fringing. Sony has also included a Nano AR Coating that minimizes flare and reflections on the optics, particularly when shooting in harsh or bright lighting conditions.

Versatile Operation

The FE 20mm f1.8 G utilizes a Dual XD Linear Motor system to drive the auto focus. The result is a quick, quiet, and accurate autofocus for stills or video use, with the ability to switch quickly to manual focus if desired via the switch on the side of the lens. There are also customizable focus hold buttons on the barrel for locking focus or rapid access to custom settings.
