Description — Canon RF 15-35mm f/2.8 L IS USM
The Canon RF 15-35mm f/2.8 L IS USM is a wide-angle zoom lens for the Canon RF mirrorless mount, covering a 15mm to 35mm focal length range on full-frame sensors. Its constant f/2.8 maximum aperture means exposure and background separation remain predictable as you zoom, which is particularly valuable in mixed or low-light environments. Built-in optical image stabilization adds an extra layer of shooting confidence for handheld work, while support for both autofocus and manual focus makes it adaptable to a wide range of photographic disciplines — from fast-moving documentary work to precise, composed landscape shots.
The 82mm filter thread is a practical inclusion for photographers who regularly use graduated ND, polarizing, or other screw-in filters. At 840g, this is a substantial lens, but one that reflects the engineering required to deliver a constant f/2.8 aperture across a demanding wide-angle zoom range on a full-frame platform.
