INCREDIBLY SHARP: Two XA (extreme aspherical) elements along with two ED (Extra Low dispersion), one Super ED and one aspherical element ensure outstanding resolution in this F1.8 prime lens delivering high corner-to-corner resolution and beautiful bokeh, making this an excellent full frame lens for landscapes, starscapes, portraits and videography. BEAUTIFULLY SMOOTH BACKGROUNDS: A circular 9-blade aperture on this 14mm lens creates beautiful circular background bokeh defocus effects with a large F1.8 aperture. 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 FE lens as a landscape lens, lens for astrophotography, or in other light-sensitive shooting scenarios. FAST AND PRECISE: Two XD (Extreme Dynamic) Linear Motors with their complex construction deliver faster and more accurate focusing than conventional lenses for both photography and videography. You won't miss a shot on this large aperture wide angle lens. PROFESSIONAL ERGONOMICS: A dust and moisture resistant design, along with versatile controls on this Sony prime lens makes it ideal to use in the most difficult scenarios - both indoors and outdoors.
