Full-Frame E-mount. As a part of the FE line of lenses, the Sony FE 20mm f/1.8 G is designed to cover the full-frame sensors on Sony a7 / a9 series cameras. Since it’s an E-mount lens, it’s also fully compatible with their crop-frame, APS-C cameras that feature an E-mount.
Versatile Ultra-Wide Prime. When used on a full-frame camera, this lens provides an ultra-wide focal length that’s excellent for portraiture, street photography, reportage, and selfies. The fast f/1.8 aperture is great for low-light shooting and subject-background isolation, while the 0.6-ft. minimum focusing distance lets you get in close. Using an APS-C camera? You’ll get a 30mm focal length.
Dual XD Linear Motor Autofocus System. This internal focusing system provides fast, nearly silent, and highly accurate autofocus performance that’s great for still and video use. A customizable focus hold button and an AF/MF switch help to tailor focusing to your shooting needs.
Advanced Optics. The FE 20mm f/1.8’s twelve-group/fourteen-element optical design incorporates two advanced aspherical elements and three extra-low dispersion elements to produce sharp, clear images. The lens’s nine-blade aperture diaphragm gives images smooth out-of-focus areas when you desire a shallow depth of field, while the Nano AR Coating reduces color fringing and aberrations
Durable, Compact Build. This lens’s durable, dust- and moisture-resistant construction and rubberized control rings mean you can use it in adverse conditions without worry. The front element has a fluorine coating to protect it from debris and smearing. You can de-click the physical aperture ring for smooth, silent aperture switching that’s ideal for video applications.
