Ultra-wide and versatile, 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.

• Ultra wide-angle zoom designed for full-frame E-mount mirrorless cameras, this lens is also compatible with APS-C models where it provides an 18-36mm equivalent focal length range.
• Constant f/4 maximum aperture offers consistent performance throughout the zoom range.
• Four aspherical elements are featured in the optical design to control spherical aberrations in order to produce a high degree of sharpness while also limiting distortion.
• One Super ED and three ED elements are used to suppress chromatic aberrations and color fringing for improved clarity and color accuracy.
• A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
• A Direct Drive Super Sonic wave Motor AF system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control.
• A dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
