The Sony power zoom E PZ 10-20mm F4 G Sony E mount is an ultra-wide-angle APS-C video lens and offers outstanding mobility and superb image quality for stills and video. With internal zoom and focus, the lens maintains the same length for zooming or focusing, with a stable center of gravity ideal for vlogs and gimbal shooting. Outstanding mobility makes it a perfect choice for a wide range of situations. Three aspherical elements reduce field curvature and astigmatism, and the aspherical ED element reduces chromatic aberration for high resolution throughout the entire image and 10-20 mm zoom range (35 mm full-frame equivalent: 15-30 mm). The natural-looking bokeh of the Sony 10-20mm F4 G can offer extraordinary expressiveness thanks to the minimum distance for AF of 0.2 m and 0.13~0.17 m for MF. The new electronic Power Zoom system instantly converts dial rotations into actual zoom to faithfully capture the intention of content creators. The zoom lever makes it easy to perform super slow zooms at constant speed difficult with manual zoom.
