The FE 135mm f/1.8 GM from Sony is a medium telephoto prime characterized by its bright and sophisticated design. The advanced optical design incorporates two extra-low dispersion elements, including one Super ED element, to reduce chromatic aberrations and one XA (extreme aspherical) element, which significantly controls spherical aberrations for a high degree of image sharpness and clarity. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions and dedicated focus hold buttons, AF/MF switch, and manual aperture ring lend further control while shooting. Additionally, these lenses feature robust and intuitive-to-handle physical designs to benefit both photography and cine applications. Bright f/1.8 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over the focus position when using shallow depth of field techniques. Two extra-low dispersion elements, including one Super ED element, are featured in the lens design and help to reduce chromatic aberrations and color fringing for improved clarity and color neutrality. An XD Linear Motor system and internal focus mechanism provide quick, quiet, and precise autofocus performance and also contribute to more natural, intuitive manual focus control. An AF/MF switch is located on the lens barrel for tactile control over this setting. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
