The Sony FE 20mm F1.8 G is an extreme fast ultra wide angle prime lens for the Sony E camera system.
The lens provides two XD (eXtreme Dynamic) Linear Motors for high AF speed (pic.5). It has a dust- and moisture-resistant design (pic.6).
Its lenses are Nano AR coated against flares and ghosting. Two advanced aspherical elements and three extra-low dispersion glass elements are employed to minimize sagittal flare.
The lens has a declick function for its aperture ring (pic.7). Unlike many other ultra-wide-angle lenses, this one has a filter mount (67mm).
