SUMMARY
Anthony Gugliotta tested Canon's RF 20-50mm f/4 L IS USM power zoom lens, weighing it against the 24-70mm and 24-105mm lenses for real-world video applications. At only 14 oz, this lens significantly reduces bulk and fatigue, making it ideal for lightweight video rigs used in vlogging, gimbal work, and handheld content creation. The lens features dual zoom controls—a barrel and a camera body rocker—that can be set to different speeds independently, allowing for cinematic crawls or quick punch-ins with improved steadiness. Its internal zoom design maintains consistent weight distribution, beneficial for gimbal balancing, and the 20mm focal length is noted as suitable for talking head shots without excessive distortion.
