Canon RF 20-50mm f/4L IS USM PZ

Canon's first full-frame L-series power-zoom lens — a non-extending design built for hybrid shooters using gimbals and sliders, with smooth motorised zoom and full L-series optics and sealing. The narrow 20-50mm range and f/4 aperture are the acknowledged trade-off for stills use; this is a video lens first.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
