FE 28–70 mm F2 GM
Sharp, refined rendering in a unique constant F2 standard zoom
Optics featuring large elements manufactured using advanced techniques, including three XA (extreme aspherical) elements, ensure high corner-to-corner resolution at F2 throughout the zoom range. One ED (extra-low dispersion) and three Super ED elements reduce chromatic aberration, Nano AR Coating II cuts flare/ghosting, floating focus boosts close-focus resolution, and gorgeous G Master bokeh enhances dimensionality.
A compact, mobile lens packed with superb optics and functionality
This compact, lightweight F2 zoom lens delivers advanced standard zoom functionality, image quality that rivals the best primes, and stunning 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 in) and weighs just 918 g (32.4 oz). Stress-free shooting with all the advantages of a standard zoom and no compromise on image quality.
Precise, tenacious AF tracking with instant response
Four XD (extreme dynamic) linear motors and the latest algorithm keep the large F2 focus group under precise control. Reliable focus tracking and instant response are essential in professional situations such as weddings or sports events where missing even one frame can be disastrous. This lens is fully compatible with the 120fps burst capability of the α9 III, and tracking continues smoothly even while zooming.
Designed for refined, expressive movie production
Focus breathing is effectively reduced for smooth movie imagery with minimal angle-of-view instability. Rack focus and zoom effects can be used with F2 depth of field to create natural transitions that guide the viewer’s eye. Critical focus for high frame rate 4K 120p/FHD 240p recording is easy. The XD linear motors and a new aperture unit are quiet in operation, and α body breathing compensation is supported.
Operability and reliability that support professional needs
Linear Response MF provides intuitive focus control, adjustable zoom ring torque allows easy customization, and an aperture ring with a click ON/OFF switch provides hands-on aperture control. Two customizable focus hold buttons offer even more flexibility. Dust and moisture resistance ensures reliability in challenging outdoor conditions, while a fluorine coating on the front element effectively repels contaminants.

FEATURES
| 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, unrivaled 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 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 1.25 ft (0.38 m) 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. Color 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 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. |
| 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 color 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 (3.75 x 5.63 in) 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 120fps 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 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 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 minimized 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. |
