High resolution rivals the best primes

Excellent contrast at high spatial frequencies means superb resolution even at F2.8. Two high-precision XA (extreme aspherical) elements, two ED (Extra-low dispersion) glass elements, two Super ED glass elements, and a floating focus mechanism control chromatic aberration, astigmatism, distortion, and coma at all zoom and aperture settings. Nano AR Coating II subdues flare and ghosting for outstanding clarity.

Stunning G Master bokeh

Exquisite F2.8 bokeh extends throughout the zoom range thanks to advanced optical design and a new 11-blade aperture unit. Bokeh is enhanced by precise control of spherical aberration during design and for each lens during manufacture. Two XA elements with 0.01-micron precision suppress onion ring bokeh. Minimum focusing distance is 0.21 meters at 24 mm and 0.30 meters at 70 mm, with max. magnification of 0.32x.

The most compact, lightweight, and versatile in its class

The smallest and lightest F2.8 24-70mm zoom in its class, this lens offers unprecedented flexibility and freedom. It weighs just 695 grams, 191 grams less than the previous model. Its length has been reduced by 16 mm, and overall volume has been reduced by approximately 18%. Impressive portability and mobility make it a good choice for professional or enthusiast still or movie use in a wide range of situations.

Fast, precise AF and excellent response

Four of Sony’s original XD (extreme dynamic) Linear Motors, a floating focus mechanism, and advanced lens control achieve high AF precision and approximately 2x better tracking performance while zooming than the previous model
. With a compatible body it can shoot at up to 30 frames per second. The new aperture unit also contributes to high speed, enabling full AF tracking performance even when shooting with the aperture stopped down.

Movie features refined for visual creators

The latest lens design technology reduces unwanted image shifts and angle of view variations for smooth, expressive movie imagery. XD Linear Motors enhance AF and tracking performance, enabling high frame rate recording for exquisite detail. Independent focus and aperture rings are provided, and Linear Response MF ensures direct, linear focus ring response when focusing manually.

Excellent control and reliability in any environment

An updated dust and moisture resistant design
provides extra reliability for outdoor use in challenging conditions, and a fluorine coating keeps the front element clean. Convenient operation of circular polarizing and variable ND filters (optional) is provided by a special opening in the supplied lens hood. Two customizable focus hold buttons are provided for easy access and convenient control when shooting in any orientation.

Lens Configuration

G Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background bokeh.
