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. Its advanced optical design includes a series of XA, aspherical, Super ED, and ED elements, which combine to reduce a variety of aberrations and distortions for a high degree of sharpness, accurate rendering, and notable color accuracy. Complementing the optics is an XD Linear Motor system that uses four separate focusing motors to deliver especially quiet, precise, and quick autofocus performance. 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. Nano AR Coating II has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. This updated coating is better suited for larger, curved elements and is especially adept at minimizing internal reflections. An XD Linear Motor system uses four separate motors two per focusing group along with an internal focusing design to provide quick, quiet, and precise autofocus and tracking performance.

This design also contributes to more natural, intuitive Linear Response manual focus control, and 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. An integrated petal-shaped lens hood helps to block stray light from causing lens flare and also affords some physical protection to the front element.
