A versatile full-frame 28-70 mm zoom for compact alpha bodiesThis small, light, full-frame zoom lens covers 28-70 mm with minimal change in lens length. One Ed and three aspherical elements suppress aberration, while a circular aperture enhances bokeh. Optical image stabilization minimizes blur in low light and telephoto captures, and in-body Active Mode1 is supported for enhanced stabilization. Dust and moisture resistance ensures reliability.Compact high-performance full-frame 28-70 mm zoomThis high-performance full-frame zoom lens covers a 28-70 mm range that is often the first choice for scenery, portraits, snapshots and much more. Despite an ideal range and superb optical performance, its largest diameter is 72.5 mm and overall length is 83 mm. With a weight of just 293 g (10.4 oz.), this remarkable lens is a compact, mobile choice for day-to-day shooting.Refined optics for lifelike renderingThree aspherical elements combine with one Ed (Extra-low Dispersion) glass element to deliver excellent optical performance throughout the zoom range. Clear, lifelike rendering has been achieved without color bleeding. A 7-blade circular aperture unit contributes to attractive, natural-looking bokeh.Bring out the best in the latest a bodiesAF/Ae tracking speed that can keep up with the 120-fps continuous burst capability of the a9 Iii, the ability to precisely track and focus even while zooming, and other features take full advantage of the advanced capabilities of the latest a series bodies. And thanks to an effective dust and moisture resistant design this is a lens you can depend on in tough conditions.a great choice for movies as well as stillsOptical image stabilisation that utilises advanced algorithms achieves excellent stabilisation for handheld shooting. Lens stabilisation also works with in-body stabilisation and Sony's Active Mode to deliver reliable stabilisation for movies. The Breathing Compensation feature provided in a series bodies is also supported, greatly reducing distracting angle of view shifts and allowing smooth rack focusing.Extra durability and reliability for challenging outdoor conditionsSilicone gaskets around all buttons and switches, a rubber ring seal for the lens mount, and other refinements constitute an effective dust and moisture resistant design that maximizes reliability in challenging outdoor conditions. The front lens element has a fluorine coating that repels contaminants and makes them easy to wipe away if they do become attached to the lens surface.Advantages of Sony's lenses for video shootingLearn the four unique advantages of using Sony's E-mount lens for video shooting.
