Canon RF 15-35mm f/2.8L IS USM Lens

Overview

The Canon RF 15-35mm f/2.8 L IS USM Lens is a professional wide-angle zoom for full-frame Canon RF-mount mirrorless cameras, pairing a versatile 15 to 35mm focal length range with a constant f/2.8 maximum aperture. Well suited to landscapes, architecture, interiors, documentary work, travel, events, and environmental portraits, it offers a broad field of view while maintaining consistent low-light capability and exposure control throughout the zoom range.

Built as part of Canon’s L-series, the lens combines advanced optics, fast Nano USM autofocus, optical image stabilisation, and weather-resistant construction for demanding stills and video use. UD and aspherical elements help control colour fringing, distortion, and spherical aberrations, while Air-Sphere Coating improves contrast when shooting into strong light. A configurable Control Ring supports intuitive exposure adjustment, and fluorine coatings on the front and rear elements help resist fingerprints, smudges, and moisture.

Core Features

• The 15 to 35mm wide-angle zoom range is ideal for landscapes, interiors, architecture, events, documentary work, and expansive establishing shots.
• A constant f/2.8 maximum aperture maintains consistent brightness throughout the zoom range for low-light shooting and controlled depth of field.
• Two UD elements and three aspherical elements help reduce colour fringing, distortion, and spherical aberrations for sharp, accurate image rendering.
• Air-Sphere Coating helps suppress flare and ghosting to maintain contrast and colour fidelity when working in bright or backlit conditions.
• Optical Image Stabilisation compensates for up to five stops of camera shake, helping deliver sharper handheld results in difficult lighting.
• Nano USM autofocus provides fast, accurate, and near-silent focusing performance for both still photography and video recording.
• The configurable Control Ring allows direct adjustment of exposure settings such as aperture, ISO, or exposure compensation from the lens.
• L-series weather-resistant construction and fluorine coatings support reliable use in challenging outdoor and professional shooting environments.

Constant f/2.8 Aperture Across the 15-35mm Range

The bright f/2.8 maximum aperture remains available across the entire zoom range, making the lens practical for available-light shooting, indoor scenes, and controlled subject separation. It also helps maintain consistent exposure when zooming during stills or video capture.

Corrective Precision via UD and Aspherical Elements

Two Ultra-Low Dispersion elements help minimise chromatic aberration and colour fringing, while three aspherical elements correct spherical aberration and distortion. This optical design supports sharp detail, clean edges, and accurate rendering across the wide-angle zoom range.

Five-Stop Stabilisation for Sharp Handheld Results

Built-in Optical Image Stabilisation compensates for up to five stops of camera shake, helping produce sharper handheld images when shooting in low light, at slower shutter speeds, or in fast-moving documentary and travel situations.

Nano USM Autofocus System

The Nano USM autofocus system combines speed, precision, and smooth near-silent operation, making the lens well suited to both stills and video. Full-time manual focus override is also available when working in one-shot AF mode.

Weather-Sealed L-Series Build and Control Ring

As an L-series RF lens, the 15-35mm f/2.8 is built for demanding professional use with weather-resistant sealing against dust and moisture. A configurable Control Ring provides quick access to key camera settings directly from the lens barrel.
