What We Like
+World's first 24-105mm f/2.8 lens combining versatile zoom range with constant bright aperture
+Excellent optical performance with sharp, detailed images throughout the zoom range
+Dual Nano USM motors deliver fast, quiet autofocus with minimal focus breathing
+Up to 8 stops of image stabilization combined with in-body stabilizer for handheld low-light shooting
+Professional-grade hybrid design with cinema-ready iris ring and power zoom adapter compatibility
+Robust L-series build with weather sealing, fluorine coating, and tripod mount
Worth Knowing
−Exceptional price point around $3,300 limits accessibility for most photographers
−Significantly larger and heavier than comparable f/4 zoom lenses, impacting portability and handling
−Requires heavy in-camera digital distortion correction, particularly at 24mm, affecting corner image quality
−Aperture ring currently only functional in video mode on existing EOS R models, not for stills photography

About This LensThe Canon RF 24-105mm F2.8 L IS USM Z is a groundbreaking hybrid lens that achieves the long-sought combination of a versatile 24-105mm zoom range with a constant f/2.8 aperture. Its sophisticated optical design, dual Nano USM autofocus, powerful image stabilization (5.5 stops optical, expandable to 8 stops with IBIS), and cinema-ready features like the iris ring make it an exceptional all-in-one solution for demanding professionals working in both stills and video. However, its premium $3,300 price tag, substantial size and weight, reliance on digital distortion correction, and current video-only aperture ring functionality may limit its appeal compared to more specialized zoom alternatives. | |
