RF 20-50mm f/4L IS USM PZ: Canon’s first full-frame RF Power Zoom lens
Canon also introduces the RF 20-50mm f/4L IS USM PZ, its first full-frame RF L-series lens with an internal power zoom.
The zoom ring operates as both a controlled, steady servo zoom while recording video and a manual zoom-by-wire for precise adjustments when capturing stills or filming. Covering a wider-than-standard 20-50mm focal range at a constant f/4 maximum aperture, this incredibly versatile lens is ideal for vlogging, interiors, and capturing superb views without changing lenses.
The RF 20-50mm f/4L IS USM PZ delivers exceptional L-series image quality, featuring UD lens elements, Air Sphere Coating (ASC), and optically suppressed focus breathing to maintain a stable frame during zooming. Weighing just 420g, it offers up to 6-stops5 of optical image stabilisation, ensuring shake-free handheld shooting. Its Nano USM autofocus provides swift, silent, and accurate focusing, down to 0.24 metres.
The professional performance is matched by intuitive on-body controls. These include a customisable Lens Function button, a manual focus ring, and a dedicated Control Ring for instant access to an assigned setting.
