The FE 85mm f/1.4 GM from Sony is a fast, short-telephoto lens designed for E-mount mirrorless digital cameras. Characterized by its flattering perspective and fast f/1.4 maximum aperture, this lens is adept at isolation focus for shallow depth of field effects, as well as performing in low-light conditions. The optical design incorporates three extra-low dispersion elements to reduce chromatic aberrations and one XA (extreme aspherical) element, which significantly controls spherical aberrations for a high degree of image sharpness and clarity. Pairing a bright f/1.4 aperture with a short-telephoto focal length, this 85mm lens is ideally suited for portraiture and other situations where focus control is paramount. For controlling focus, a linear SSM (Super Sonic wave Motor) is employed that is quick and quiet, and also lends more responsive control for manual focus operation. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions and a dedicated focus hold button, AF/MF switch, and manual aperture ring lend further control while shooting. A portrait-length prime designed for full-frame E-mount mirrorless cameras, this 85mm f/1.4 is also compatible with APS-C models where it will provide a 127.5mm equivalent focal length. One XA element is incorporated into the optical design, which features superior surface precision for effective control over astigmatism, field curvature, coma, and other spherical aberrations. A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. A focus hold button is present on the lens barrel for intuitive tactile control and rapid access to select settings. Dust and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
