Frequently Asked Questions

  • A power zoom lens uses a motor or servo to provide a fluid and consistent zoom speed. It's a real advantage for video recording, allowing you to start and stop the zoom smoothly and achieve more stable footage when reframing your shots. Another benefit of a power zoom versus a manual zoom, is that it can be operated by a camera that has a zoom lever or rocker, such as the Canon EOS R6 V, EOS R50 V and EOS C50. Remote operation is also possible, using a compatible controller or software app. For example, the RF 20-50mm F4L IS USM PZ's power zoom can be operated using a smartphone or tablet, via Canon Camera Connect – perfect for zooming in and out when you're presenting to the camera or carrying out an interview.

  • Canon has developed an innovative mechanism that makes it quick and easy to move between power zoom and manual zoom on the RF 20-50mm F4L IS USM PZ. Both types of zoom are operated using the single zoom ring on the lens – you simply hold down the PZ/MZ switch and rotate the zoom ring to move between the two modes.

  • The RF 20-50mm F4L IS USM PZ is a high-quality standard zoom lens that's optimised for video without holding back your photography. Ideal for creative content makers, it covers a range of popular focal lengths but runs even wider than typical standard lenses. It's a flexible option for daily vlogs, filming interiors, capturing cinematic views and behind-the-scenes clips. It focuses close too – right down to 0.24 metres – so you can be even more creative with your framing.
