Canon RF 9521B002 24-105mm
The STM motor delivers smooth, near-silent autofocus for video, while the 4-stop image stabilizer keeps handheld shots steady across the 24–105mm range. Weighing just 525g, it’s among the lightest full-frame zooms, with manual focus override and optimized coatings that enhance contrast. Best for budget-conscious hybrid shooters who prioritize a portable, stabilized zoom for landscapes, travel, and video, but don’t need wide-aperture isolation for portraits.
