Bright, versatile F2 standard zoomThe first G Master standard zoom with constant F2 aperture is ideal for portraits and many other subjects. Sharpness and contrast match a fixed focal length lens, while the brightness of F2, unrivalled AF, a versatile zoom range and compact, lightweight design offer an exceptional creative range for stills and video.Sharpness that maximises the body's potential Sophisticated design and optical simulation provide a fixed focal length quality zoom. The large elements manufactured with original technology, including three XA (extreme aspherical) elements, enable high resolution right up to the edge of the image at F2 across the entire zoom range. The floating focus enables focussing distances of 0.38 m/1.25 ft throughout the zoom range.Chromatic aberration control.One ED (extra-low dispersion) element and three Super ED elements reduce axial chromatic aberration as well as lateral chromatic aberration, which can reduce resolution at the periphery of the image. Colour bleeding is effectively suppressed throughout the image area for exceptional clarity and resolution, and reflections and ghosting are minimised with Sony's original AR Nano Coating II, resulting in clear images even in strong backlighting. Specially designed optics to prevent internal reflections improve reflection suppression and ensure precise clarity, even when strong light sources shine into the frame. Perfect for portraits, sports, videos, live events and more.
