The FE 14mm f/1.8 GM from Sony is a fast, versatile lens well-suited to landscape, natural, architectural, and astrophotography applications. Its extremely wide-but-usable perspective is complemented by the f/1.8 maximum aperture for excellent performance in low-light conditions and increased control over the depth of field. The optical design incorporates two extra-low dispersion elements and one super ED element to reduce chromatic aberrations, plus two XA (extreme aspherical) elements that significantly control spherical aberrations for a high degree of image sharpness and clarity. A minimum focus of just 9.8" and an ultra-wide field of view opens a new world of deep perspective close-up photography. Also, the lens features a dust- and moisture-sealed design and fluorine-coated outer elements to support shooting in inclement conditions.  The versatile ultra-wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras; however, it can also be used on APS-C models where it provides a 21mm equivalent focal length. Two XA (extreme aspherical) elements, and one standard aspherical element, are incorporated into the optical design, which features superior surface precision for effective control over astigmatism, field curvature, coma, distortion, and other spherical aberrations for a high degree of sharpness and accurate rendering.

Nano AR Coating II has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. This updated coating is better suited for larger, curved elements and is especially adept at minimizing internal reflections. A focus hold button is present on the lens barrel for intuitive tactile control and rapid access to select programmable settings. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures. The filter holder is incorporated at the rear of the lens, within the lens mount, and accepts cut gel filters, and a filter cutting template is included.
