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. 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. 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.
