Canon RF 20-50mm F4 L IS USM PZ

Canon RF 20-50mm F4 L IS USM PZ

The Canon RF 20-50mm f/4 L IS USM PZ combines an ultra-wide-angle and standard zoom range with the optical quality and durability of Canon's L-series. Covering focal lengths from 20mm to 50mm, it is suitable for a wide range of shooting situations, including landscapes, interiors, architecture, travel, documentaries and professional video production.

A constant f/4 maximum aperture ensures consistent exposure throughout the zoom range, while the integrated Power Zoom system delivers smooth, precise and repeatable zoom movements that are particularly valuable for filming and live streaming. The Nano USM autofocus motor offers fast, accurate and near-silent focusing for both stills and video.

Optical image stabilization helps reduce camera shake when shooting handheld, resulting in sharper images and smoother video. When used with compatible Canon EOS R cameras featuring In-Body Image Stabilization (IBIS), stabilization performance is further enhanced.

Built to Canon's professional L-series standards, the lens features a weather-resistant construction, high-quality optics with advanced coatings to reduce flare and ghosting, and customizable control functions for efficient operation in challenging shooting environments.
