FE 12–24 mm F2.8 GM
At the 12-mm end of its range, this 12–24-mm constant F2.8 zoom lens offers an ultra-wide angle of view. An innovative optical design works with Sony's advanced XD Linear Motors to deliver outstanding G Master image quality in a lightweight lens that also features fast, precise auto focus, smooth control and solid reliability.
The ultra-wide 12-mm angle of view available with this versatile lens makes it possible to emphasise distance and create dynamic perspectives that are beyond the scope of the human eye. Expand your artistic palette with deep, engaging visual imagery.
Three XA (extreme aspherical) elements, including the largest ever made, combine with one aspherical element in an innovative optical design that achieves stunning G Master resolution throughout the image area. Two Super ED (Extra-low Dispersion) and three ED glass elements suppress chromatic aberration, and a new Nano AR Coating II minimises flare and ghosting for clear, crisp imagery.
12–24-mm zoom with a constant F2.8 maximum aperture is ideal for shooting night scenes, starry skies and other low-light subjects at low sensitivities without having to use extremely slow shutter speeds.
An advanced optical design with four aspherical elements, including three XA types, plus a mechanical design that features Sony's original XD linear motors, in a compact, lightweight 12–24-mm constant F2.8 zoom that delivers stunning image quality. In addition to being ideal for landscapes, night scenes and architecture, this lens provides extra mobility for active sports photographers who shoot wide angles.
Four XD Linear Motors, two for each of the lens's focus groups, contribute to fast, precise auto focus and tracking that make use of the speed potential provided by high-performance α camera bodies. New control algorithms maximise the response of the XD Linear Motor system while achieving flawless synchronisation between the focus groups. Operation is also quiet with minimal vibration.
A focus hold button, focus mode switch, zoom ring, focus ring and other controls are designed and positioned for easy operation and a smooth workflow. Alternative functions to support the user's individual shooting needs can be assigned to the focus hold button via camera body menu settings. A fluorine front element coating plus a dust- and moisture-resistant design ensures high reliability in challenging environments.
G Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background bokeh
