Combining the versatility of a zoom with the speed typically reserved for a prime, the Canon RF 28-70mm f/2L USM Lens is a wide-angle to portrait-length lens distinguished by its impressively unique f/2 constant maximum aperture. This bright design yields excellent low-light performance along with enhanced control over depth of field for isolating subject matter. Ultra-Low Dispersion glass is employed in the optical design, and greatly reduces color fringing and chromatic aberrations in order to realize high clarity and color accuracy. Complementing the advanced optical properties is Canon's proven ring-type Ultrasonic Motor, which delivers fast and quiet autofocus performance along with full-time manual focus control. Additionally, unique to RF lenses, this 28-70mm incorporates a configurable Control Ring for intuitively adjusting exposure settings, including ISO, aperture, and exposure compensation, from the lens itself. {Key Features} - RF-Mount Lens/Full-Frame Format - Aperture Range: f/2 to f/22 - Ultra-Low Dispersion Elements - Ring-Type Ultrasonic Motor AF System - Customizable Control Ring - Rounded 9-Blade Diaphragm {Box Contents} - Canon RF 28-70mm f/2L USM Lens - E-95 95mm Lens Cap - Lens Dust Cap RF - EW-103 Lens Hood - LP1424 Lens Case
