The Sony FE 24-70mm f/2.8 GM Zoom Lens is built with three aspherical elements including a newly developed extremely precise XA (extreme aspherical) element that reduces aberration and delivers the ultimate resolution throughout the entire zoom range and aperture range. An ED (Extra-low-Dispersion) glass element and Super ED glass element keep chromatic aberration to a minimum while maximizing resolution and bokeh without any unnatural coloration. To maximize usability this lens also features a dust/moisture resistant design AF/MF switch circular aperture Nano AR coating compact and a direct drive SSM (Super Sonic wave Motor) focusing system.
