The Sony FE 24-70mm f/2.8 GM (SEL2470GM) is a standard zoom lens in Sony's G Master line. It is made for full-frame Sony E-mount cameras and covers wide-angle to short telephoto focal lengths. The constant f/2.8 aperture keeps exposure and depth-of-field control consistent across the zoom range.
The optical design uses an XA (extreme aspherical) element, additional aspherical elements and ED glass to reduce aberrations. A Nano AR coating reduces flare and ghosting. A Direct Drive Super Sonic Wave Motor drives the autofocus for stills and video.
The lens has dust- and moisture-resistant construction. Physical controls include a focus hold button, an AF/MF switch and a zoom lock switch.
