Fast F2.8 APS-C standard zoomSony’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.High resolution throughout the zoom range, even at F2.8Two 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.Compact, lightweight, and brightOptimized mechanical and optical design achieve a weight of just 17.5 oz (494 grams) 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.XD Linear Motor for fast, precise AF and trackingThe same type of advanced XD (extreme dynamic) linear motor that maximizes focus performance in G Master series lenses is employed in this APS-C lens. The XD Linear Motor fully utilizes the speed potential of the camera body, focusing on and tracking even fast-moving subjects with outstanding speed and precision. Operation is also quiet, allowing videographers to take advantage of the constant F2.8 aperture.Professional control and reliabilityA customizable focus hold button, AF/MF mode switch, and Linear Response MF add control versatility and precision that can help get the shot even in difficult, changing conditions. The front lens element is fluorine coated to repel water and grime, and the lens is dust and moisture resistant3 so that that it can be used with confidence in challenging outdoor environments.Lens ConfigurationImpeccable Sony G Lens design emphasizes a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist’s vision.MTF ChartMTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
