The Sony FE 28-70mm F2 GM features a standard zoom range and a constant f2 maximum aperture, making it ideal for portraits and many other subjects. Its F2 aperture, superb optics, and mobility will appeal to even the most demanding pros. Sharpness and contrast rival prime lens quality, while brightness, unrivalled AF, zoom, and a compact, lightweight design offer extraordinary creative scope for stills and movies.
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 3-3/4 x 5-5/8 in (92.9 x 139.8 mm) and weighs just 32.4 oz (918 g). 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.
