The Sony FE 24-70mm f/2.8 GM II is Sony's second-generation fast standard zoom for full-frame E-mount cameras. It is 22% lighter and 18% smaller than the original G Master, with four XD linear motors and a floating focus group for fast, quiet autofocus. XA and Super ED elements plus Nano AR Coating II target sharpness and flare control across the zoom range. It suits wedding, event and portrait shooters who want one fast lens instead of several primes; against the Sigma 24-70mm f/2.8 DG DN it trades a higher outlay for a lighter body and faster AF, and reviewers rate it among the sharpest standard zooms for E-mount.

Owners and reviewers rate the GM II as one of the best standard zooms for Sony full-frame, praising its sharpness, fast and quiet autofocus and the weight saving over the original. Complaints center on the size of the 82mm filters and the lack of optical stabilization.
The Sony FE 24-70mm f/2.8 GM II is a full-frame E-mount standard zoom lens with a constant f/2.8 maximum aperture. It is 22% lighter and 18% smaller than the previous generation. Its optics, focusing system and handling have been updated.
The optical design uses two ED and two Super ED elements to suppress chromatic aberration and color fringing. Five aspherical elements, including two extreme aspherical (XA) elements, minimize spherical aberration and distortion and reduce onion-ring bokeh. Nano AR Coating II controls flare and ghosting, and a fluorine coating is also applied. An 11-blade circular aperture diaphragm produces smooth, circular bokeh at all aperture settings.
Four XD Linear Motors drive the autofocus, which supports shooting at up to 30 fps. Full AF is maintained when shooting stopped down, and focus tracking works while the zoom position changes. A floating focus mechanism helps maintain image quality across the focusing range, and internal focusing keeps the lens length constant during operation. Focus breathing, focus shift and axial shift during zooming are minimized for video. The lens has aperture de-click and lock switches, a zoom smoothness switch, and dust- and moisture-resistant construction.
