Combining the versatility of a zoom with the speed typically reserved for a prime, the Canon RF 28-70mm f/2 L 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 depth of field for isolating subject matter.
RF28-70mm f/2L USM features an additional control ring on the barrel that could be customised to control exposure settings; shutter speed, aperture, ISO and exposure compensation, effectively providing better control especially while shooting through the Electronic View Finder. The control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback during adjustment.
