Fast F2.8 APS-C standard zoom, High resolution throughout the zoom range, even at F2.8, Compact, lightweight, and bright, XD Linear Motor for fast, precise AF and tracking, Professional control and reliability,

Sony's first 16 - 55-mm (24 - 82.5 mm full-frame equiv.) APS-C zoom with a constant F2.8 aperture is remarkably compact while offering performance befitting the G Lens series. A new optical design delivers excellent corner-to-corner resolution, and beautiful bokeh is available when needed. It is compact, lightweight, and ideal for a wide range of subjects.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. Sony's original Nano AR Coating adds superior resistance to flare and ghosting for crisp contrast. Precise spherical aberration control and a 9-blade circular aperture contribute to smooth bokeh.
