The Sony 16-55mm F2.8 G is a versatile, compact and lightweight, wide-angle to portrait-length zoom lens featuring a bright constant f/2.8 maximum aperture. This 16-55mm lens features an XD Linear Motor system for fast and quiet AF. It has a dust and moisture sealed design and fluorine coating to support shooting in bad weather conditions. Excellent G Lens resolution Two AA (advanced aspherical) and two aspherical elements suppress aberration for outstanding corner-to-corner G Lens resolution, while three ED (Extra-low Dispersion) glass elements reduce color bleeding to a minimum. You get sharp, clear detail and natural colour throughout the zoom range at any focusing distance. Smooth, beautiful bokeh Spherical aberration has a large effect on bokeh quality, and is precisely controlled to deliver smooth, attractive bokeh in out-of-focus areas. A 9-blade circular aperture also contributes to this lenss beautiful bokeh. Sharp in-focus detail contrasts with luscious background bokeh for deep, impressive imagery. Crisp contrast Sonys original Nano AR Coating creates a precise, regular nanostructure on lens surfaces that does not interfere with light transmission while suppressing reflections that can cause flare and ghosting. Internal reflections are reduced to an absolute minimum, achieving outstanding clarity and contrast. Compact, lightweight Optimised mechanical and optical design achieve a weight of just 494 g (17.5 oz.) in a compact, constant F2.8 16-55 mm (24-82.5 mm full-frame equiv.) zoom lens. This fine lens is ideal for everything from portraits to everyday snapshots, combining with compact E-mount bodies to form a highly mobile, manageable system for a wide range of photographic applications. Fast, precise AF and tracking The same type of Sony's advanced XD (eXtreme Dynamic) linear motor used in G Master series lenses is employed in this lens. The XD Linear Motor fully utilises the speed potential of the camera body, focusing on and tracking even fast-moving subjects with outstanding speed and precision. Fluorine coated front element The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface. Linear Response MF Sonys Linear Response MF feature ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise. Dust and moisture resistant A dust and moisture resistant design2 provides the reliability needed for outdoor use in challenging conditions. MFR ref: SEL1655G Sony e16-55mm f2.8 g lens in Black
