The Sony FE 12-24mm f/2.8 GM is a bright and versatile zoom characterized by its broad range and bright design. Featuring a constant f/2.8 maximum aperture, this lens is ideal for working in available lighting conditions and controlling depth of field to isolate subject matter. An updated Nano AR Coating II has also been applied, which suppresses flare and ghosting for greater contrast when working in bright and backlit conditions. A floating focus design is employed, too, that aids in maintaining consistent results throughout the focusing range, from 11" to infinity. The lens also sports a dust- and moisture-sealed design and fluorine-coated front lens element to support shooting in inclement conditions and there is a built-in petal-shaped lens hood to block stray light and physically protect the front element. Versatile ultra-wide-angle zoom is designed for full-frame Sony E-mount mirrorless cameras, however can also be used on APS-C models where it provides an 18-36mm equivalent focal length. Three 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. The floating focusing system divides the focus group into two separately controlled groups and helps to maintain consistently clear optical performance throughout the zoom and focus ranges.
