The FE 12-24mm f/4 G Lens from Sony is a flexible zoom lens for full-frame Sony E-mount mirrorless cameras, characterized by its constant f/4 maximum aperture. Benefitting the wide field of view is a sophisticated optical design that incorporates aspherical and low dispersion glass elements to control both spherical and chromatic aberrations for improved sharpness and clarity. A Nano AR Coating has also been applied to individual elements to reduce surface reflections, flare, and ghosting for greater contrast and color fidelity when working in bright, backlit situations.

In addition to the optical attributes, this lens is also distinguished by a Direct Drive SSM autofocus system, which benefits both stills and video application with its quick, quiet, and precise performance. 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.
