The Canon RF 15-35mm f/2.8L IS USM is a professional wide-angle zoom lens designed for the RF mount, making it compatible with both full-frame and APS-C cameras. Its constant f/2.8 maximum aperture allows you to maintain consistent exposure settings across the entire focal range while providing enough light for challenging environments. To ensure sharpness and clarity, the optical system utilizes 16 elements arranged in 12 groups, paired with a Nano USM autofocus motor for fast, quiet focusing. Built to withstand demanding conditions, this lens features weather sealing and a sturdy construction that weighs 840 g. The integrated image stabilization provides up to 5 stops of shake correction, which is particularly helpful when shooting handheld in low light or capturing steady wide shots. It measures 126.8 mm in length and uses an 82 mm filter size, coming bundled with the EW-88F lens hood, a cap, and a protective case. With a minimum focus distance of 28 cm, you can get remarkably close to your subjects for impactful compositions. This makes it a versatile choice for landscape photographers who need an expansive 110° diagonal angle of view or architects capturing interior spaces where room is limited.
