Features

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 lens 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.

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.

Fluorine Coating

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.

High-speed Communication with the EOS R Camera

Designed to quickly process data, the RF 28–70mm F2 L USM features a 12 pin communication system that is the fastest yet for a Canon lens/camera combination. This accelerates AF, Image Stabilization, the Digital Lens Optimizer and more, helping to simplify complex operations and provide a quick and reliable user experience.

Lens Information Display

Another helpful feature, the EOS R camera can display lens information right in the viewfinder, making it easy to confirm the lens's focal length without looking away from the subject at hand.

In-camera Digital Lens Optimizer

The EOS R system's 12 pin communication system enables the Digital Lens Optimizer, which works in-camera to combat aberrations and image deterioration, especially in the edges of the image frame when shooting at a large aperture. Data from the RF 28–70mm F2 L USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.

The RF 28–70mm F2 L USM features an all-new optical design built specifically for the RF mount. This includes four aspheric lenses that correct for aberrations, distortions and astigmatism, plus two UD elements and one Super UD element to reduce chromatic aberration and achieve high image quality across the board. Strategically placed coatings and a 9-blade aperture help ensure superlative quality images with sharp detail, gorgeous color and minimized distortion throughout the zoom range.

The RF 28–70mm F2 L USM lens features Canon's Air Sphere Coating (ASC), which significantly reduces the occurrence of lens flare and ghosting regardless of focal length or the angle of light. This helps provide clean results with minimal distractions and aberrations.

MTF Charts

A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners. For more information on understanding how to read Canon Lens MTF charts, please click here.
