Description

Introducing the Sony FE 20-70mm F4 G.
The Sony FE 20-70mm F4 G is a standard zoom lens with an ultra-wide angle, in an ultra-compact and lightweight form factor. It boasts an extended focal length range of 20-70mm and a constant F4 aperture. It combines the image quality characteristic of the G series, silent, fast, and precise autofocus with subject tracking, and an optimized design that maximizes portability and ergonomics.
Its sophisticated optical design incorporates 16 elements in 16 groups, including two AA (Advanced Aspherical) elements, one aspherical element, three ED (Extra-low Dispersion) glass elements, and one ED aspherical glass element. Its advanced optical formula simultaneously corrects chromatic and spherical aberrations, ensuring extremely high optical performance at all focal lengths. Optimized surface coatings add excellent resistance to flare and ghosting, ensuring exceptional clarity and contrast for this advanced optical formula. It also benefits from a 9-blade circular diaphragm that delivers beautiful bokeh.
The lens’s focusing group is driven by two XD linear motors (contactless magnetic motors), a cutting-edge technology that provides high torque for fast, quiet, and vibration-free driving. Their efficiency has been significantly improved compared to previous models, accelerating autofocus by up to 60%. Furthermore, with tracking performance doubled compared to previous models, moving subjects are tracked reliably and accurately in real time. Tracking remains reliable even when shooting fast-moving objects in a 30fps burst with the Sony Alpha 1, and video recording remains smooth even at high frame rates.
The Sony FE 20-70mm F4 G incorporates the latest optical technologies to reduce focus breathing and optical axis shifts during zooming, ensuring flawless video image capture.
