An F2 standard zoom that rivals prime lens quality¹

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 (3.75 x 5.63) and weighs just 918 g (32.4 oz). Stress-free shooting with all the advantages of zoom and no compromise on image quality.

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.

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 120fps³ 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 240p⁴ recording is easy. The XD linear motors and a new aperture unit operate quietly, and α body breathing compensation⁵ is supported.

Sharpness that maximises body potential

Advanced design and optical simulation result in zoom quality that rivals prime lenses². 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 1.25 ft (0.38 m) throughout the zoom range.

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.
