As part of Canon’s flagship L-series lineup, this lens is designed to meet the needs of professional photographers and serious enthusiasts who demand the best from their equipment.

Design and Build

The RF 24-70mm f/2.8L IS USM boasts an impressive build quality that reflects its premium status. The lens features a durable magnesium alloy body with a robust design that feels solid in the hand. The weather-sealed construction ensures that it can withstand harsh environments, making it ideal for outdoor and wildlife photography.

The lens’s ergonomic design incorporates a comfortable grip and intuitive controls, including an advanced focus ring with a subtle texture for precise control. Additionally, Canon has included a customizable control wheel that allows users to adjust settings such as aperture, shutter speed, or ISO without having to access the camera’s menu system.

Optics

The RF 24-70mm f/2.8L IS USM features an advanced optical design with 17 elements in 12 groups, including two fluorite elements and one UD (Ultra-Low Dispersion) element. This complex arrangement ensures that the lens delivers exceptional image quality across its zoom range.

At 24mm, the lens offers a wide field of view with minimal distortion and excellent sharpness. As you zoom towards 70mm, the lens maintains its sharpness and contrast, making it suitable for portraits, street photography, or candid shots.

Image Stabilization

The RF 24-70mm f/2.8L IS USM features Canon’s advanced Image Stabilization (IS) system, which provides up to 5 stops of correction against camera shake and blur. This feature is particularly useful for handheld shooting, low-light photography, or when using slower shutter speeds.

Autofocus and Aperture

The lens incorporates a fast and accurate autofocus motor with a minimum focusing distance of 0.38 meters (1.25 feet). The aperture range spans from f/2.8 to f/22, allowing users to adjust the exposure settings according to their creative vision.

Additional Features

The RF 24-70mm f/2.8L IS USM also includes several advanced features that enhance its performance and versatility:
