The Sony FE 28-70mm F2 GM is a fast standard zoom that trades 4mm from the wide end for an aperture that's a stop brighter than the classic 24-70 F2.8. It is Sony's first constant F2 zoom for its E-mount cameras.
The lens's optical formula consists of 20 elements in 14 groups, with three aspherical lenses, three super ED elements, and one ED element. It uses an 11-blade aperture. The front element has an oil and water-resistant fluorine coating, and the lens is moisture and dust resistant. It weighs 918g, and is 140mm long.
It also has features that video shooters will appreciate, such as a clickless aperture ring, linear response focus ring, and internal focusing.
