Overview Ultra wide and versatile, the Sony FE 12-24mm f/4 G Lens 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.
