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 0.24‑m minimum focus enables stunning close-ups.

Designed for polished movie imagery

In addition to smooth, versatile power zoom, this remarkably compact lens minimizes jarring angle-of-view shifts that can occur when focusing or zooming so that stable, high-quality movie footage can be easily captured. Focus, zoom and aperture operation are also extremely quiet, greatly reducing noise and vibration that can interfere with movie recording.

Smooth power zoom with snappy response

A new power-zoom system driven by four XD 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.

Three-ring control: zoom, focus and aperture

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.
