Sony FE 12-24mm F2.8 GM ( SEL1224GM) is a full-frame large-aperture ultra-wide zoom lens, ideal for shooting landscapes, astrophotography and architecture while providing extra mobility for active sports shooters who want to capture ultra-wide perspectives. As part of Sony's flagship G Master series lenses, users can be completely confident that it delivers outstanding image quality up to an ultra-wide 12mm angle of view with F2.8 constant aperture and beautiful bokeh effects.

The FE 12-24mm F2.8 GM benefits from innovative construction that delivers outstanding corner-to-corner image quality throughout the entire zoom range. It features three precise XA (extreme aspherical) elements including the largest XA element ever made for an Alpha brand lens. These XA elements, with an additional aspherical element, effectively suppress astigmatism, coma and field curvature right out to the image edges. Furthermore, three ED (Extra-low Dispersion) glass elements plus two Super ED glass elements, powerfully control chromatic aberration and combine to deliver corner-to-corner clarity while minimizing color fringing.

An extremely effective floating focus mechanism divides the lens's focus group into two independently controllable groups, ensuring both outstanding close-up performance and maximum sharpness at any distance. The two independently controlled groups help realize a constant 28 cm minimum focusing distance throughout the zoom range, and because it is an internal focus lens, its length remains constant, so its center of gravity varies very little and is always optimally balanced in the hand.

The signature bokeh effects of Sony's G Master series lens are achieved through the fine tuning of the lens's spherical aberration characteristics during both the design and manufacturing process. At the same time, the extremely high surface precision of the lens's XA elements effectively suppresses spherical aberration and, in combination with a 9-blade circular aperture, further enhances its exquisite bokeh.

The FE 12-24mm F2.8 GM employs four original high-speed, high-thrust XD (extreme dynamic) Linear Motors to ensure that it is compatible with the speed performance of both current and future camera bodies. With two XD Linear Motors for each of the lens's focus groups, autofocus is fast and precise. New control algorithms maximize the response of the system while achieving flawless synchronization between the two focus groups. Further benefits include extremely quiet operation with minimal vibration and lower power consumption.

A brand-new Nano AR Coating II that can be evenly applied to large lens elements or highly curved element surfaces has been used for the first time on the FE 12-24mm F2.8 GM. It suppresses internal reflections, minimizes flare and ghosting for clear, crisp imagery and despite the lens's wide angle of view, Nano AR Coating II maintains high clarity and contrast throughout the entire image, even in difficult light.

The constant F2.8 maximum aperture at all focal lengths ensures that exposure is stable when zooming. As a result, this means that shutter speed and ISO sensitivity can remain constant while shooting movies. The creative opportunities afforded by shooting movies at a 12mm angle of view with F2.8 constant aperture in full-frame are boundless, and when used on an APS-C or Super 35 camera, the wide end of the zoom range becomes equivalent to 18mm, providing a useful zoom range for moviemaking.

Weighing only 847 g, the FE 12-24mm F2.8 GM offers numerous features for full professional control of shots. These include a customizable focus-hold button, focus-mode switch, zooming ring and focusing ring that are positioned for easy operation while shooting. The Linear Response MF ensures that the focus ring responds directly to the most subtle adjustments when focusing manually so control feels immediate and precise. It is dust and moisture resistantiii and the front lens element features a fluorine coating that repels water, oil, and other contaminants, making it easier to wipe off any fingerprints from the lens surface. The rear filter holder accommodates standard sheet-type ND, color correction and other filters for expanded expressive capability. A cutting template for sheet filters is supplied.
