The Sony FE 12-24mm f/2.8 GM is a premium ultra-wide-angle zoom lens for Sony E-mount full-frame cameras.
The lens offers a 12-24mm focal length range that covers a 122° to 84° angle of view, ideal for landscapes, architecture, interiors and astrophotography.
The lens has a constant f/2.8 aperture that enables low-light performance and shallow depth of field effects.
The lens delivers high image quality with a sophisticated optical design that incorporates three XA (extreme aspherical) elements, one aspherical element, two super ED (extra-low dispersion) elements, three ED elements and one fluorite element.
These elements help to reduce chromatic aberrations, distortions, spherical aberrations and coma, and enhance sharpness and clarity across the frame.
The lens also features a Nano AR Coating II that suppresses flare and ghosting, and improves contrast and color accuracy.
The lens has a durable and lightweight metal barrel that measures 97.6 x 137 mm and weighs 847 g.
The lens has a dust- and moisture-resistant construction that includes rubber seals around the mount and buttons.
The lens has a focus hold button, an AF/MF switch, a zoom lock switch and a rear filter holder that accepts gel filters.
The lens has a Direct Drive SSM (Super Sonic wave Motor) that provides fast and quiet autofocus performance, with full-time manual focus override for fine-tuning.
The lens has a rounded nine-blade diaphragm that creates smooth and pleasing bokeh effects.
The lens is compatible with Sony’s 1.4x and 2x teleconverters that extend the focal length to 17-34mm or 24-48mm respectively, with one-stop or two-stop loss of light respectively.
