Canon RF 28-70mm f/2 L USM Lens

The Canon RF 28-70mm f/2L USM 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 the 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.  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. 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. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
