A Bright, Versatile F2 Standard Zoom
The first6 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 quality1, while F2 brightness, unrivalled AF, a versatile zoom range, and a compact, lightweight design offer extraordinary creative scope for stills and movies.
Sharpness That Maximizes Body Potential
Advanced design and optical simulation result in zoom quality that rivals prime lenses1. 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.
F2 G Master Design For Extraordinary Depth
Advanced design and optical simulation result in zoom quality that rivals prime lenses1. 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.
Constant F2 In A Compact, Lightweight Lens
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.
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 fps2 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 240p3 recording is easy. The XD linear motors and a new aperture unit operate quietly, and α body breathing compensation4 is supported.
Chromatic Aberration Controlled
Sony’s original Nano AR Coating II minimizes 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.
Resistant To Flare And Ghosting
Sony’s original Nano AR Coating II minimizes 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.
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 customizable 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 moisture5 and ensure maximum reliability in challenging outdoor conditions. A fluorine coating on the front element effectively repels contaminants and makes cleaning easy.
