This is a super-telephoto zoom lens for Sony E-mount APS-C cameras. It covers 70-350mm, which is equivalent to 105-525mm on a full-frame camera. It weighs 22 oz (625 g).
The optical design uses one aspherical element and three Extra-low Dispersion (ED) glass elements. These suppress aberration across the zoom range, including chromatic aberration at long focal lengths. They also reduce flare and ghosting and help keep edges free of fringing. Optical SteadyShot image stabilization is built in, and the diaphragm has 7 blades.
An XD (extreme Dynamic) linear motor drives autofocus. It is the same type used in G Master series lenses, and it focuses on and tracks moving subjects quickly and quietly. Linear Response MF ties focus movement to the angle of ring rotation for repeatable manual focus, which is useful in video. An AF/MF switch on the side of the lens changes between auto and manual focus.
