The first 70 - 300 mm E-Mount zoom lens offers outstanding resolution across the entire image area. Thanks to a minimum focusing distance of just 0.9 m, breathtaking, detailed close-ups are possible. The integrated SteadyShot image stabilization compensates for camera shake throughout the zoom range, and a modern linear actuator ensures fast, precise autofocus. Furthermore, the lens is dust and moisture resistant. A range of 70 mm to 300 mm covers a wide variety of subjects, from portrait and landscape photography to sports and nature shots. When used with an APS-C camera, 300 mm becomes a 450 mm super-telephoto focal length. Sony's unique G lens strikes a balance between excellent resolution and fabulous background bokeh, opening up new artistic perspectives for the photographer. MTF (Modulation Transfer Function) is a measure of how well a lens can reproduce fine details - measured as contrast ratio.
