New Speed & Resolution In An F1.2 LensThis 50-mm F1.2 G Master prime lens is a creator's dream, with an F1.2 maximum aperture that not only allows shooting in a wider range of lighting conditions, but also provides an extraordinary combination of high resolution, luscious G Master bokeh, and blazing autofocus. It is also remarkably compact and lightweight-for new creative freedom.G Master Resolution Without CompromiseThe compact, lightweight FE 50 mm F1.2 GM is an ideal choice for dedicated creators. XA (extreme aspherical) elements and other advanced technologies combine to achieve extraordinary resolution and contrast from the image center right out to the edges. Sony Nano AR Coating II subdues flare and ghosting, while a floating focus mechanism ensures optimum sharpness at any focusing distance.Smooth, Refined G Master BokehXA elements plus painstaking spherical aberration control at the design and manufacturing stages contribute to gorgeous G Master bokeh that can really make portrait and other subjects stand out, especially with the shallow depth of field available at the lens's maximum F1.2 aperture. An 11-blade circular aperture mechanism contributes to beautifully circular bokeh.Fast, Precise, Quiet AF & TrackingFast, accurate focus is assured, even with extremely shallow 50 mm F1.2 depth of field. Four XD (extreme dynamic) Linear Motors smoothly deliver high thrust to position the large, heavy focus groups for fast, accurate AF. Original Sony E-mount lens technology ensures that you get maximum performance from E-mount bodies-for both stills and movies.Professional Mobility3.5" (87 mm) in diameter, 4.38" (108 mm) long, and weighing just 27.5 oz (778 g), the FE 50 mm F1.2 GM complements compact, high-performance E-mount bodies to create a system that gives serious shooters the mobility and handling. Three XA elements and four XD Linear Motors in a large-aperture lens that is surprisingly compact offer extraordinary creative potential.Professional Control & ReliabilityTwo focus hold buttons, a focus mode switch, a focus ring, an aperture ring with switchable click stops and other controls support smooth operation. The focus hold buttons can be assigned to other functions via a camera menu. Linear Response MF ensures that the focus ring responds linearly to manual focus control. Effective dust and moisture resistance and a fluorine front element coating enhance reliability.
