This compact, lightweight, full-frame constant F4 wide-angle power zoom lens delivers superb G Lens image quality. It includes two AA (advanced aspherical) elements, a Super ED (Extra-low Dispersion) element, and an ED element to effectively suppress distortion and aberration. A circular aperture and controlled spherical aberration enhance bokeh quality, while 9.5-inch (0.24 meter) minimum focus enables stunning close ups.

A new power zoom system driven by four XD (Extreme Dynamic) Linear Motors for the first time in an α lens provides smooth control with the immediacy of manual zoom. Even subtle zoom ring rotation is precisely detected and instantaneously converted to zoom operation. A continuously variable zoom lever makes it easy to execute super-slow constant-speed zooms, and zoom can be remotely controlled while the camera is mounted on a gimbal.²

Two XD (extreme dynamic) Linear Motors deliver quick, quiet, low-vibration autofocus while maintaining compact lens dimensions. Tenacious, reliable AF can smoothly track subjects while shooting high frame rate photos or movies. With a compatible body³ it is possible to maintain accurate focus while shooting stills continuously at up to 30 frames per second and movies up to 120fps. Subjects are smoothly tracked even while zooming.

Independent zoom, focus, and aperture rings on this compact lens offer flexible, intuitive creative control. Responsive zoom control is indispensable for movies, and Linear Response MF ensures that the focus ring responds directly to subtle control when focusing manually. The aperture ring has an aperture click switch that allows the click stops to be turned off when smooth, seamless aperture adjustment is required.

Although this compact wide-angle zoom lens weighs just 353 g (12.5 oz), it does not compromize functionality or performance in any way. Its length remains constant while focusing and zooming for optimal balance and handling, which also makes it ideal for gimbal-mounted movie shooting or with the use of a matte box. Impressive portability and a dust/moisture resistant design⁴ make it a great choice for just about any subject or situation.
