High Image Quality

Thanks to the large-diameter RF mount and short back focus design, the RF 24-70mm F2.8 L IS USM lens features a balanced and comfortable design for an ease of operation use, and amazing performance in various lighting situations, even in low-light areas to deliver detailed images at various focal lengths.

Bright f/2.8 Aperture Standard Zoom RF L Lens

With a constant f/2.8 maximum aperture, 21 elements in 15 groups and a 9-blade aperture system, The RF 24-70mm F2.8 L IS USM lens is engineered to deliver sharp and stunning images with gorgeous background blur and remarkable consistency – ideal for portrait photography.

Optical Image Stabilization of up to 5 Stops* of Shake Correction

The RF 24-70mm F2.8 L IS USM lens is the first Canon brand 24-70mm F2.8 lens (for full-frame cameras) to incorporate Optical Image Stabilization. This lens is designed to work in conjunction with an EOS R series camera, with both the camera and the lens sharing data to dramatically reduce camera-shake blur, regardless of the situation, whether shooting video or stills. With up to 5 stops* of stabilization, it delivers impressively clear results.

* Based on CIPA (Camera & Imaging Products Association) standards. Testing performed at a focal length of 70mm using the EOS R camera.

High Speed, Smooth and Quiet Auto Focus with Nano USM

The RF 24-70mm F2.8 L IS USM lens is equipped with Canon's NANO USM system, which features a diminutive chip-shaped ultrasonic motor that's engineered to help deliver high-speed, smooth, precise and near-silent operation, during still image AF and smooth movie AF.

Minimum Focusing Distance of 0.69 ft./0.21m (wide), 1.25 ft./0.38m (tele)

With a zoom range that can cover a minimum focusing distance at 0.69 ft./0.21m (wide), 1.25 ft./0.38m (telephoto), and a maximum magnification of approx. 0.30x* the RF 24-70mm F2.8 L IS USM lens offers amazing versatility with just the turn of a zoom ring. The RF 24-70mm F2.8 L IS USM lens is capable of capturing sharp and detailed images from nearly any distance.

Control Ring for Direct Setting Changes

The RF 24–70mm F2.8 L IS USM lens has a separate, independent control ring that is located towards the front of the lens, which can be programmable for immediate exposure adjustments during still and video shooting. With the control ring, you can directly adjust settings such as shutter speed, lens aperture, exposure compensation and more. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee.

12 pin Communication System

High-speed Communication with the Camera

Designed to quickly process data, the RF 24–70mm F2.8 L IS USM features a 12 pin communication system that is the fastest yet for a Canon lens/camera combination. This accelerates AF, Image Stabilization, the Digital Lens Optimizer and more, helping to simplify complex operations and provide a quick and reliable user experience.

Lens Information Display

Another helpful feature, the EOS R series cameras can display lens information right in the viewfinder, making it easy to confirm the lens’s focal length without looking away from the subject at hand.

In-camera Digital Lens Optimizer

The EOS R system’s 12 pin communication system enables the Digital Lens Optimizer, which works in-camera to combat aberrations and image deterioration, especially in the edges of the image frame. Data from the RF 24–70mm F2.8 L IS USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.

Three Aspherical Elements and Three UD Elements

Taking advantage of the RF mount, the RF 24–70mm F2.8 L IS USM lens offers incredible optical quality and an exceedingly bright f/2.8 maximum aperture. It features 3 aspheric lenses for high image quality from center to corner and 3 UD lenses that helps reduce aberrations for minimized distortion throughout the image plane.

Air Sphere Coating (ASC) Minimizes Lens Flare and Ghosting

The RF 24–70mm F2.8 L IS USM lens features Canon's Air Sphere Coating (ASC), which significantly reduces the occurrence of lens flare and ghosting regardless of focal length or the angle of light. This helps provide clean results with minimal distractions and aberrations.

Dust- and Weather- resistant with Fluorine Coating

Dust- and Weather-resistant

The RF 24-70mm F2.8 L IS USM lens features a dust- and weather-resistant construction in the lens mount, switch panel and all rings. Sealing is applied to lens joining sections, and switch panels to help prevent water and dust from entering into the lens.

Fluorine Coating

Featuring fluorine coatings on the front and rearmost surfaces to help prevent dirt and dust from sticking to the lens, the RF 24-70mm F2.8 L IS USM lens makes it easy to clean smudges and fingerprints off.

High Reliability and Durability for Professional Use

The RF 24-70mm F2.8 L IS USM lens is built to endure the rigors of professional use. Constructed to be rugged, refined and precise, it can be operated intuitively so concentration can remain on the subject at hand.

Vibration Shock Resistance

The RF 24-70mm F2.8 L IS USM lens features L series level vibration shock resistance in the lens barrel, helping to maintain focus and settings even in turbulent situations.
