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.
