A bright, versatile F2 standard zoom

The first G Master™ 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, while F2 brightness, unrivalled AF, a versatile zoom range, and a compact, lightweight design offer extraordinary creative scope for stills and movies.

Sharpness that maximises body potential

Advanced design and optical simulation result in zoom quality that rivals prime lenses. 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.

Chromatic aberration controlled

One ED (extra-low dispersion) element and three Super ED elements reduce axial chromatic aberration as well as lateral chromatic aberration that can reduce resolution at the image periphery. Colour bleeding is effectively suppressed throughout the image area for exemplary overall clarity and resolution.

Resistant to flare and ghosting

Sony’s original Nano AR Coating II minimises flare/ghosting, making it possible to shoot clear images even in strong backlighting. Optics designed to suppress internal reflections provide further flare resistance, ensuring high clarity whenever a strong light source appears in the frame. Perfect for portraits, sports, movies, live events, and more.

F2 G Master design for extraordinary depth

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 colour bleeding are effectively suppressed for refined image quality.

Constant F2 in a compact, lightweight lens

This versatile standard zoom lens delivers image quality that rivals prime lenses plus amazing AF. Innovative technologies including advanced 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.

Precise, reliable, responsive AF tracking

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 burst capability of the α9 III, and tracking continues even while zooming.

Refined, expressive movie production

Focus breathing is subdued for refined movie imagery. Rack focus and zoom effects can be used with F2 depth of field to create smooth, natural transitions. Critical focus for high frame rate 4K 120p/FHD 240p recording is easy. The XD linear motors and a new aperture unit operate quietly, and α body breathing compensation is supported.

Professional control

Important control functions include Linear Response MF for intuitive manual focus, adjustable zoom ring torque, and an aperture ring with a click ON/OFF switch. There are also two customisable focus hold buttons, an iris lock switch, and an AF/MF switch. Filter diameter is 86 mm, and the lens hood has a window for easy variable filter operation. 

Rugged and reliable

Buttons and switches feature silicone gaskets, the lens mount includes a rubber ring, and all other critical areas are painstakingly designed to prevent the incursion of dust and moisture and ensure maximum reliability in challenging outdoor conditions. A fluorine coating on the front element effectively repels contaminants and makes cleaning easy.

Environment friendly

Sony’s “Road to Zero” project aims for a zero environmental footprint by 2050. The environmental footprint of this product has been minimised from development through supply chain, production, and packaging. We are also transitioning to non-plastic packaging materials. Plant-based non-woven fabrics are used for product bags.
