The Canon RF 24-70mm f/2.8 L IS USM is Canon’s definitive professional standard zoom lens for full-frame RF-mount mirrorless cameras, delivering a constant f/2.8 maximum aperture across the entire zoom range for outstanding low-light performance and precise depth-of-field control. Built as an L-series workhorse, it combines three aspherical and three Ultra-Low Dispersion elements with Air Sphere and Fluorine coatings to render strikingly sharp, color-accurate images with minimal flare, ghosting, or chromatic aberration.
Engineered equally for photographers and videographers, the lens features Canon’s advanced Nano USM autofocus system for fast, near-silent focusing, an Optical Image Stabilizer providing up to 5 stops of shake compensation, a customizable Control Ring for instant exposure adjustments, and a weather-sealed, dust- and moisture-resistant construction — making it one of the most versatile and reliable lenses in the RF lineup.
Key features
- Constant f/2.8 Aperture: Maintains consistent brightness and exposure from 24mm to 70mm, ideal for low-light shooting and beautiful background separation with selective focus.
- 5-Stop Optical Image Stabilizer: Compensates for camera shake by up to five stops, enabling sharp handheld shots at slower shutter speeds in challenging lighting conditions.
- Nano USM Autofocus: Combines a ring-type USM and STM mechanism for fast, precise, and near-silent AF — perfect for both stills and video — with full-time manual focus override in One-Shot AF mode.
- Advanced Optical Design: Three aspherical elements correct spherical aberration and distortion, while three UD elements suppress chromatic aberration and color fringing for exceptional clarity across the zoom range.
- Air Sphere & Fluorine Coatings: ASC minimizes flare and ghosting in backlit conditions; the fluorine coating on front and rear elements resists fingerprints and smudges for easier maintenance.
- L-Series Build & Customizable Control Ring: Weather-sealed against dust and moisture for professional use in any environment, with a configurable Control Ring to adjust aperture, ISO, or exposure compensation directly from the lens.

Frequently asked questions
Is the Canon RF 24-70mm f/2.8 L IS USM compatible with Canon EOS R full-frame mirrorless cameras?
Yes, this lens uses the Canon RF mount and is specifically designed for Canon's full-frame RF-mount mirrorless cameras, such as the EOS R5, R6, and R3 series, delivering full functionality including autofocus, image stabilization, and the Control Ring.
How effective is the image stabilization on the Canon RF 24-70mm f/2.8 L IS USM?
The lens features a built-in Optical Image Stabilizer that compensates for up to 5 stops of camera shake, allowing you to shoot handheld at significantly slower shutter speeds than would otherwise be possible — particularly valuable in low-light situations.
Is the Canon RF 24-70mm f/2.8 L IS USM suitable for video recording?
Absolutely. The Nano USM autofocus system — which combines a ring-type USM and an STM mechanism — delivers smooth, fast, and near-silent focusing that minimizes focus noise during video capture, while the 5-stop image stabilizer and constant f/2.8 aperture further support handheld cinematic shooting.
