The FE 16-35mm f/2.8 GM Lens from Sony is a wide-angle zoom designed for full-frame E-mount mirrorless cameras. Distinguished by its constant f/2.8 maximum aperture, this lens offers consistent performance throughout the zoom range and benefits working in low-light conditions. The optical design incorporates two extra-low dispersion elements to reduce chromatic aberrations along with two XA elements and three aspherical elements, which significantly controls spherical aberrations for a high degree of image sharpness and clarity.  For controlling focus, two Direct Drive SSM AF groups are employed that are quick and quiet, and also lend 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 and AF/MF switch. Wide-angle zoom designed for full-frame E-mount mirrorless cameras, this lens is also compatible with APS-C models where it provides a 24-52.5mm equivalent focal length range. Two XA (extreme aspherical) elements and three aspherical elements are 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. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures. Additionally, the front element has a fluorine coating to guard against fingerprints and dust from adhering to it.
