The Canon RF 28-70mm f/2 L USM lens seamlessly merges the adaptability of a zoom lens with the rapidity typically associated with prime lenses. This wide-angle to portrait-length lens is notable for its exceptional constant maximum aperture of f/2. Such a luminous design provides outstanding performance in low-light conditions and offers enhanced depth of field control, allowing for effective subject isolation. The optical construction utilizes Ultra-Low Dispersion glass, significantly minimizing color fringing and chromatic aberrations, thereby achieving remarkable clarity and color fidelity. Further enhancing its optical capabilities is Canon's renowned ring-type Ultrasonic Motor, which ensures swift and silent autofocus, along with the option for full-time manual focus. Additionally, this 28-70mm lens features a customizable Control Ring, a distinctive aspect of RF lenses, enabling users to intuitively modify exposure settings such as ISO, aperture, and exposure compensation directly from the lens.
