INCREDIBLY SHARP: Two XA (extreme aspherical) elements ensure outstanding resolution in this F1.4 prime lens. Along with one aspherical element, it delivers high corner-to-corner resolution and beautiful bokeh, making this an excellent full frame lens for landscapes, starscapes and videography. BEAUTIFULLY SMOOTH BACKGROUNDS: A circular 11-blade aperture creates beautiful circular background bokeh defocus effects with a F1.4 large aperture lens. AMAZING CLARITY AND CONTRAST: Even under strong sunlight and backlighting, Sony’s new Nano AR Coating II is evenly applied to the element surface, effectively minimising internal reflections so that flare and ghosting do not occur when using this Sony G Master Lens. FAST AND PRECISE: Two XD Linear (Extreme Dynamic) Motors with their complex construction deliver faster and more accurate focusing than conventional camera lenses for both photography and videography. Whether using it as a landscape lens or portrait lens, and even in low light, you won't miss a shot with this FE lens. PROFESSIONAL ERGONOMICS: A dust and moisture resistant design, along with versatile controls on this GM lens makes it ideal to use in the most difficult scenarios - both indoors and outdoors.
