Sony FE 28-70mm F2 GM Lens Black SEL2870GM

The first*6 G MasterTM standard zoom with a constant F2 aperture is ideal for portraits and a wide range of other subjects. Sharpness and contrast rival prime lens quality*1, while F2 brightness, unrivalled AF, a versatile zoom range, and a compact, lightweight design offer extraordinary creative scope for stills and movies.
Advanced design and optical simulation result in zoom quality that rivals prime lenses*1. Large elements including three XA (extreme aspherical) elements manufactured using original techniques ensure high corner-to-corner resolution at F2 throughout the zoom range. Floating focus allows close focus down to 0.38 m/1.25 ft throughout the zoom range.
An F2 max. aperture and G Master optics deliver exquisite, soft bokeh for deep, dimensional images. Spherical aberration is carefully controlled for ideal resolution/bokeh balance, and a new 11-blade circular aperture unit helps to deliver gorgeous ball bokeh. Onion-ring bokeh and color bleeding are effectively suppressed for refined image quality.
This versatile standard zoom lens delivers image quality that rivals prime lenses plus amazing AF. Innovative optics and XD (extreme dynamic) linear motors make all of this fit in a constant F2 zoom that is only 92.9 x 139.8 mm (3-3/4 x 5-5/8) and weighs just 918 g (32.4 oz). Stress-free shooting with all the advantages of zoom and no compromise on image quality.
Four XD (extreme dynamic) linear motors and the latest algorithm precisely control the large F2 focus group. Reliable focus tracking and instant response are essential at weddings or sports events where every frame counts. This lens is fully compatible with the 120 fps*2 burst capability of the α9 III, and tracking continues even while zooming.
