Video-Ready Zoom A fast, lightweight power zoom lens, the Canon RF 20-50mm f/4 L IS USM PZ Lens is designed for content creation, where it delivers exceptional video performance with the option to choose between power zoom and manual zoom. Fully compatible with any RF-mount body, the lens has a wide f/4 to f/22 aperture range at all focal lengths, six stops of optical image stabilization, and a nano USM focusing motor to deliver optimal results no matter the subject. Crystal Clear Optics Focus breathing is extremely controlled for optimal video performance. The lens element features a fluorine coating, and the lens body is dust and weather-resistant with an internal zoom for use in any environment. Two aspherical and three ultralow dispersion elements work together to render a sharp, distortion-free image throughout the zoom range, while a 9.5" minimum focus distance allows detailed close-ups. Power Zoom Control The incorporated wide-to-tele rocker power zoom is powered by dual nano USM motors. Control the zoom speed in the R6 V camera's menu with separate controls for barrel speed and level speed, as well as for standby speed and recording speed. When zooming, the center of gravity shifts minimally, making it ideal for use with gimbals. A separately available BR-E2 Bluetooth remote can be purchased to enable remote zoom control.
