It's made for photographers and moviemakers who want a bright view, sharp detail, gorgeous blur and the professional performance of Canon's L series.
Bright, Constant f/2 USM Zoom Lens
For a stunningly bright f/2 aperture throughout the zoom range, look no further than the amazing RF 28-70mm F2 L USM. It is the world's first autofocus zoom lens compatible with 35mm full frame sensors to have a maximum f/2 aperture*. Thanks to the large-diameter RF mount and short back focus design, the RF 28-70mm F2 L USM also features a balanced and comfortable size for unfettered operation, amazing performance in low-light areas and sharp images with gorgeous background blur at various focal lengths.
High Image Quality at f/2 that Rivals the EF 24-70mm f/2.8 at f/2.8
Thanks to an optical design made possible by the RF mount, the RF 28-70mm F2 L USM lens is able to render image quality at f/2 that rivals that of the EF 24-70mm f/2.8 at f/2.8. With an extra stop of light, this means faster shutter speeds or lower ISOs for enhanced image quality, and marvelous performance when shooting movies.
High Precision and Flexibility to Match Fixed Focal Length Lenses
With a brilliant optical design and speedy performance, the RF 28-70mm F2 L USM delivers the flexibility, performance and image quality of 28mm, 35mm, 50mm and 70mm fixed focal length lenses in one discreet package. Combining the outstanding performance, brightness and versatility of several focal lengths into one lens, the RF 28-70mm F2 L USM lens performs with reassuring consistency, especially in high-pressure situations where quality matters and there's no time for lens changes.
Control Ring for Direct Setting Changes
The RF 28-70mm F2 L USM lens incorporates a control ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R camera's main dial and quick control dial, the control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee.
High Reliability and Durability for Professional Use
Like all L series lenses, the RF 28-70mm F2 L USM lens is built to endure the rigors of professional use. Constructed to be rugged, refined and precise, it can be operated intuitively so concentration can remain on the subject at hand.
Vibration Shock Resistance
Engineered to accommodate its optical system, the RF 28-70mm F2 L USM lens features L series level vibration shock resistance in the lens barrel, helping to maintain focus and settings even in turbulent situations.
Dust- and Water-resistant
For reliable performance even when weather conditions get difficult, the RF 28-70mm F2 L USM lens features dust- and water-resistant construction in the lens mount, switch panel and all rings.
The RF 28-70mm F2 L USM lens features fluorine coatings on the front and rearmost surfaces to help prevent dirt and dust from sticking to the lens, making it easy to clean smudges and fingerprints off.
