Canon RF 24-240mm f/4-6.3 IS USM Lens

Compact, Lightweight 10x Zoom RF Lens
With a high-magnification of 10x optical zoom and offering coverage from 24mm wide-angle to 240mm telephoto, the RF 24–240mm F4-6.3 IS USM is a perfect all-in-one travel lens that can be used for any number of shooting scenarios. From landscapes to snapshots and videos, and anything else that catches your eye, the RF 24–240mm F4-6.3 IS USM range is highly adaptable.

High Image Quality and Bright f/4-6.3 Lens Aperture
With an incredibly bright focal length lens, the RF 24-240mm F4-6.3 IS USM distinguishes itself by maintaining incredibly high image quality, edge to edge, even wide open at its f/6.3 maximum aperture. With 21 elements in 15 groups and a 7-blade aperture system, it can deliver sharp and detailed images with gorgeous background blur and remarkable consistency.

Optical Image Stabilization with up to 5 Stops* of Shake Correction
The RF 24–240mm F4-6.3 IS USM lens is designed to work in conjunction with the EOS R series cameras, 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 using the EOS R mirrorless camera at a focal length of 240mm. The number of stops may vary based on the camera model used.

High Speed, Smooth and Quiet Auto Focus with Nano USM
The RF 24-240mm F4-6.3 IS USM uses Canon's NANO USM system which combines conventional ring USM AF, and features a diminutive chip-shaped ultrasonic motor that's engineered to help deliver high-speed, smooth, precise and near-silent operation, plus full time manual focus (when using One-shot AF).

First Canon Lens with Dynamic IS for Full-frame Cameras**
Helping to deliver a wide range of image stabilization correction, the RF 24-240mm F4-6.3 IS USM lens is the first Canon lens that features Dynamic IS for full-frame cameras**. The built-in Image Stabilization helps enhance performance, even in low-light situations, and is especially effective when recording videos.
**  This function is effective during Movie Mode. 

Minimum Focusing Distance of 1.64 ft./0.50m (Wide), 2.56 ft./0.78m (Tele.)
Featuring a minimum focusing distance of 1.64 ft./0.50m (Wide) and 2.56 ft./0.78m (Telephoto) with a maximum magnification of approx. 0.26x*, the RF 24-240mm F4-6.3 IS USM is capable of capturing sharp and detailed images from nearly any distance. Whether you’re shooting videos, still images of landscapes, close ups, or a range of scenes while traveling, the RF 24-240mm F4-6.3 IS USM can easily provide sharp images with minimal distortion.

Control Ring for Direct Setting Changes***
The RF 24-240mm F4-6.3 IS USM lens incorporates a control/focus ring*** on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the end of the lens, the control/focus ring has a tactile, easily distinguished surface and provides tangible feedback for confident use while looking through the viewfinder. The RF 24-240mm F4-6.3 IS USM lens does not have the clicking mechanism as the previous RF lenses have, providing smooth focusing and exposure control while recording videos.
*** The Control ring is the same as the Focusing ring

12 pin Communication System 

High-speed Communication with the Camera
Designed to quickly process data, the RF 24-240mm F4-6.3 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 when shooting at a large aperture. Data from the RF 24-240mm F4-6.3 IS USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.
