Sony has just released the brand new FE 20mm f/1.8 G: a lightweight, high-performance, ultra-wide prime lens for full-frame Sony mirrorless cameras that the company has dubbed “the widest full-frame prime lens in E-mount lineup.”
The 20mm f/1.8 G promises excellent performance in a compact, weather-sealed package. Optically, the lens is made up of 14 elements in 12 groups, including two advanced aspherical (AA) elements and three extra-low dispersion (ED) elements to address aberration and deliver a crisp image across the entire frame. Focus relies on two extreme dynamic (XD) linear motors that should deliver fast and accurate autofocus, and the 9-blade aperture can be de-clicked using a switch on the lens barrel.
Despite the lens small size—it only weighs 373g (13.2 oz)—Sony promises “excellent close up performance” with a minimum focus distance of 7.5 inches, and accurate reproduction of point light sources with “high contrast and minimum sagittal flare” for astrophotographers.
Here’s a quick intro to the new Sony FE 20mm f/1.8 G:
