- Standard wide-angle to 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 color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy throughout the zoom range.
- 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.
- 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.
