Prime-like Performance, Zoom Versatility

The 28-70mm f/2 GM is a truly unique addition to the GM range of optics. With a constant f/2 maximum aperture, the lens provides powerful background defocus and low-light performance across its significant focal length range. Despite its remarkable technical specifications, the 28-70mm f/2 GM is a highly portable lens, weighing in at just 918g; far lighter than any comparable optic. As a result, the lens is a powerful option for any professional seeking to add some of the qualities that prime lenses offer, while maintaining the versatility that only a zoom lens provides.

Double the Light-Gathering of other Premium Zooms

To create an f/2 zoom in such a compact design, Sony engineers have employed all of the tools available; three Aspheric elements and three Extreme Aspheric elements (six total) are employed to minimise the number and size of elements required for the design. Stringent quality control ensures minimal onion-ring effect from aspheric inclusion, and the power of Sony’s XD Linear motors allows fast and silent autofocus even with large and heavy focusing elements. With this combination of technologies, the 28-70mm f/2 GM represents the pinnacle of Sony’s lens engineering.

Rapid, Tenacious Autofocus

Equipped with four XD linear motors in two focusing groups, the 28-70mm f/2 GM pairs perfectly with even the most demanding Alpha bodies, providing both powerful responsiveness and fine control for stills and video.

Designed for Stills and Video

Thanks to an aperture click selector and minimal barrel extension with zoom, the 28-70mm f/2 GM fits smoothly into a video production environment. With minimal focus breathing and unique optical properties, it offers an all-in-one option for filmmakers.

Capture clear images with minimal flare

Not only does this lens offer prime-like resolution across the image frame, it is also highly optimised for pleasing and consistent defocus, with minimal longitudinal chromatic aberration, and smooth, non-distracting rendering of background elements.
