Sony FE 28-70mm F/2 GM Lens (SEL2870GM)

A Groundbreaking Constant F2 Zoom

The Sony FE 28-70mm F2 G Master Lens (SEL2870GM) is a full-frame standard zoom built for photographers who want the speed of a prime combined with the flexibility of a zoom. It combines a constant f/2 maximum aperture with G Master optics, giving you exceptional low-light performance and background separation across the entire zoom range.

Designed for Speed and Flexibility

This lens is made for shooters who don't want to compromise between aperture speed and focal range. Maintaining a constant f/2 aperture from 28mm to 70mm, it lets you shoot in challenging light and achieve prime-like subject isolation, all without needing to swap lenses between wide and standard focal lengths.

G Master Optical Performance

The SEL2870GM uses an advanced optical design with XA (extreme aspherical) elements and ED glass to control aberrations and maintain sharpness edge-to-edge, even wide open. Its circular aperture blades produce smooth, high-quality background blur, a hallmark of the G Master line, making it well suited for portraits, events, and low-light work.

Fast, Precise Autofocus

The lens features multiple XD (extreme dynamic) linear motors that deliver fast, accurate, and quiet autofocus, making it capable of tracking moving subjects reliably for both stills and video. An aperture ring, focus hold buttons, and a manual focus ring provide added control for precise, deliberate shooting.
