Canon L RF 20-50mm f/4 L IS USM PZ 50mm
Combining an internal power zoom with a constant f/4 aperture and 6-stop stabilization, this 420g lens is Canon’s first full-frame RF L-series optic to start at 20mm. A dual-operation switch allows seamless toggling between manual and powered zoom driven by dual Nano USM actuators, while the 9-blade aperture and 0.33x magnification add practical versatility. It is best for solo video shooters and gimbal operators who need silent, parfocal-like zoom control without external rigging.
