It is the first Premium “S” Series lens, which signifies end-users will be given superior optical-technology to meet their photography needs. Its versatile standard zoom angle of view allows for flexibility to take photos at frequently desired angles and vantage points, without limitations on what is captured. The 16-50mm has an extremely bright aperture (F2.0 at 16mm; F2.8 at 50mm) making it the brightest 3X zoom among equivalent class lenses, adding-value to the overall picture-taking experience and imaging results.

Coupled with its optical image stabilizer and combination of three aspherical (ASP) lenses, two extra-low dispersion (ED) lenses, and two eXreme High Refractive (XHR) lenses, the 16-50mm F2-2.8 S ED OIS has the ability to take a steady shot and produce an exceptional photo with ultimate clarity and detail. The combination of these advanced elements work together to enhance the results from the lens. The ASP lenses reduce and nearly eliminate spherical aberration, whereas the ED elements reduce chromatic aberration and the XHR allows for a more compact and light lens.
