Extended 70 mm to 350 mm zoom range
This lens’s 70–350 mm (105–525 mm 35 mm full-frame equivalent) zoom range offers plenty of coverage for a wide spectrum of subjects, from landscapes to wildlife and more.
Superb image quality at any focal length
One aspherical element and three ED (Extra-low Dispersion) glass elements in a precision optical design suppress aberration throughout the lens’s zoom range, including chromatic aberration that can be an issue at super-telephoto focal lengths. Excellent sharpness and rendering are achieved at all focal lengths, throughout the image area.
Gorgeous G Lens bokeh
A circular aperture mechanism enhances bokeh quality, making it possible to take advantage of the narrow depth of field available with a super-telephoto zoom lens to create impressive images with smooth, gorgeous G Lens bokeh.
Compact, mobile 5x super-telephoto zoom
Although it offers a big 5x zoom range, this compact lens weighs in at just 625 grams, maximising the mobility of the entire camera system. 
XD Linear Motor in an APS-C lens
Sony’s XD (extreme dynamic) linear motor technology is available in an APS-C lens, offering top-class AF performance that is fast, precise and tenacious. Coupled with the real-time AF capability of the latest compact APS-C bodies, you have a high-performance, easy-handling system for landscapes, wildlife and more.
Clear, blur-free images without a tripod
Built-in Optical SteadyShot image stabilisation makes it easier to capture blur-free images, particularly when shooting at super-telephoto focal lengths. [1] SteadyShot OFF [2] SteadyShot ON
