The Canon RF 28-70mm f/2L USM is a versatile zoom lens that provides the speed of a prime with its impressive constant maximum aperture of f/2. This bright design allows for excellent low-light performance, along with greater control over the depth of field for isolating subjects. Utilizing Ultra-Low Dispersion glass, this lens minimizes chromatic aberrations and fringing in order to achieve high clarity and accurate colours. Canon's ring-type Ultrasonic Motor ensures smooth, quiet autofocus performance with full time manual focus control. Additionally, the Control Ring on RF lenses gives users the ability to adjust exposure settings, such as ISO, aperture, and exposure compensation, directly from the lens.

Features:

Standard wide-angle to a short-telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.

Impressively bright f/2 maximum aperture maintains consistent illumination throughout the zoom range and suits working in low-light conditions as well as affords increased control over depth of field for working with selective focus techniques.

Ultra-Low Dispersion (UD) elements are featured in the optical design and help to suppress colour fringing and chromatic aberrations in order to achieve greater clarity and colour accuracy throughout the zoom range.

A ring-type Ultrasonic Motor (USM), along with an internal focusing design, optimized focusing algorithms, and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.

Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.

As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.

The rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
