The Canon RF 28-70mm f/2L USM Lens is a wide-angle to portrait-length lens that combines the versatility of a zoom with the speed typically reserved for a prime. The lens is renowned for its unique f/2 constant maximum aperture, a bright design that is excellent for use in low-light shooting situations. Additionally, the lens offers enhanced control over depth of field for isolating subject matter. Color fringing and chromatic aberrations are greatly reduced thanks to the Ultra-Low Dispersion glass employed in the optical design, which allows you to realize high clarity and color accuracy in your stills. Canon has added to this lens their proven ring-type Ultrasonic Motor, which offers fast and quiet auto-focus performance, as well as full-time manual focus control. Another feature added onto this lens is the configurable Control Ring that allows for adjusting exposure settings, including ISO, aperture, and exposure compensation, from the lens itself.
