Ultralight, versatile wide-angle power zoom Sony's vast expertise brings you world's lightest full-frame F4 wide-angle power-zoom lens, giving today's content creators refined imagery, expression, and control. A new power zoom system in a compact lens is suitable for small crews or solo shooting. It is ideal for stills too, with beautiful G lensTM rendering and astonishing AF performance. Product Highlights: Ultralight, versatile wide-angle power zoom G lens Two AA elements, a standard aspherical element, and one ED aspherical element for high resolution throughout the image area Two XD Linear Motors offering high thrust for quick, quiet, low-vibration AF A new zoom system powered by four XD Linear Motors offering smooth control and immediate response Three ring control (zoom, focus, and aperture) and other features support professional shooting needs Product Features: Full-frame 16-35mm F4 powered zoom At only 353 g (12.5 oz) this is the world's lightest 2 full-frame F4 wide-angle power-zoom lens, yet it gives still shooters and movie content creators extraordinarily refined imagery, expression, and control. It features beautiful G Lens rendering, amazing AF performance, and a new power zoom system using four XD Linear Motors in a compact lens. High resolution in a compact lens Two AA (advanced aspherical) elements, a standard aspherical element, and one ED aspherical element suppress distortion and aberration for excellent optical performance throughout the image area. Corner-to-corner image clarity and sharpness are outstanding. Accurate color & high contrast An advanced optical design that includes one Super ED (Extra-low Dispersion) glass element, and one ED glass element subdues chromatic aberration for crisp contrast throughout every image with minimal colour bleeding. Rendering is clear and natural with any subject and lighting. Stable movies with minimal breathing State-of-the-art lens technology reduces focus breathing and jarring angle of view shifts when focusing and zooming to facilitate high-quality movie recording and smooth, refined expression. The breathing compensation function provided in compatible α series bodies is also supported. Refined G Lens bokeh A 7-blade circular aperture and carefully designed spherical aberration work together to deliver smooth, deep full-frame bokeh that can add impressive atmosphere and visual impact. Excellent close-up performance The use of AA (advanced aspherical) elements in an advanced optical design results in excellent close-up performance throughout the lens's zoom range. A minimum focusing distance of 0.24 m (0.79 ft) with 0.23x maximum magnification and constant length make this lens an excellent choice for table-top photography. Fast, precise, quiet AF and tracking Two XD (extreme dynamic) Linear Motors deliver high thrust for quick, quiet, low-vibration autofocus. Tenacious, reliable AF can smoothly track subjects when shooting high frame rate movies, and with a compatible body4 accurate focus is maintained while shooting stills continuously at up to 30 frames per second. Consistent balance for easy handling Thanks to refined internal focus and zoom mechanisms, the lens's length remains constant while focusing and zooming for ideal balance and handling. Consistent balance makes this lens an ideal choice for gimbal-mounted movie shooting. Smooth, responsive power zoom A new zoom system powered by XD Linear Motors provides smooth control and immediate response. A continuously variable zoom lever makes it easy to execute smooth constant-speed zooms, and zoom can be remotely controlled while the camera is mounted on a gimbal. Smooth remote power zoom In addition to the convenience of being able to use assignable buttons and controls on compatible bodies or a remote commander and accessory grips for convenient power zoom control, the Imaging Edge MobileTM application can be used to remotely control zoom while the camera is mounted on a gimbal. Versatile zoom for stills too Precisely controllable zoom is an advantage for stills as well as movies. The zoom ring allows quick, easy framing, and with compatible camera bodies the zoom ring direction can be customized to suit personal preference and shooting conditions. Natural, linear manual focus response Linear Response MF ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise when shooting stills or movies. Aperture click and iris lock switches An aperture ring provides direct, intuitive control. The aperture ring click stops can be turned ON to provide tactile feedback when shooting stills, or OFF for smooth, silent control when shooting movies. Fluorine front element coating The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface. Dust and moisture resistant design A dust and moisture resistant design provides extra reliability for outdoor use in challenging conditions.
