Comprising a range of ultra-wide fields of view, 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. 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.

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.
