Ultra-Smooth Motorized Power Zoom

The Canon RF 20-50mm F/4 L IS USM PZ incorporates a motorized zoom mechanism powered by dual Nano USM motors. This technology ensures exceptionally smooth and silent zoom movements, perfectly suited for professional video recording.

The center of gravity shifts minimally while zooming, making the lens highly suitable for gimbal, stabilizer, and handheld video rig use.

An optional Canon BR-E2 Bluetooth remote controller also allows remote zoom operation.
