Exquisite detail from 70 to 350 mm
Optimized optical and mechanical design offers outstanding super-telephoto zoom performance for APS-C bodies (105–525 mm equiv.). Impressive G Lens quality is maintained throughout the zoom range right out to the image edges. All of this is packed into a compact, mobile 5x super-telephoto zoom lens with built-in optical image stabilization.

G Lens quality all the way to 350 mm (525 mm equiv.)
One aspherical element and three ED (Extra-low Dispersion) glass elements in a precision optical design suppress aberration throughout the zoom range, including chromatic aberration that can be an issue at super-telephoto focal lengths. Excellent sharpness and rendering are achieved at all zoom settings, throughout the image area. Gorgeous telephoto G Lens bokeh is another advantage. 

Compact, mobile 5x super-telephoto zoom
Although it offers a big 5x zoom range, this compact lens weighs in at just 22.05 oz, enhancing the mobility of the entire camera system. 70–350 mm (105–525 mm equiv.) is an ideal range for a wide spectrum of subjects. Built-in optical image stabilization makes it easy to capture crisp, blur-free imagery even when shooting handheld at super-telephoto focal lengths.

XD Linear Motor in an APS-C lens
Sony’s original XD (extreme dynamic) linear motor technology has been applied in an APS-C lens, offering top-class autofocus performance that is fast, precise, and tenacious. Coupled with the advanced real-time AF capability of the latest compact APS-C bodies, you have a high-performance, easy-handling system for landscapes, wildlife, and more.

Control, reliability, and mobility for any situation
An Optical SteadyShot switch, customizable focus hold button, and zoom lock switch add control convenience to a lens that also features a dust and moisture resistant design2 for high reliability in challenging environmental conditions. All of this complements the lens’s portability, making pro-class control and dependability available wherever you go.

Lens Configuration
Impeccable Sony G Lens design emphasizes a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist’s vision.

MTF Chart
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
