Features

Overview: The Canon RF 28-70mm f/2 L USM standard zoom lens for the new R-series mirrorless cameras. The lens is ideal for portraits, weddings, landscapes, nightscapes, and movies. It features a constant maximum aperture of f/2 throughout the zoom range for unrivaled performance. It not only performs in low-light areas, but provides sharp focus and beautiful background blur at various focal lengths. The RF 28-70mm lens comes with a lens hood and soft case.

Lens Construction: The lens is constructed of 19 lens elements in 13 groups. The lens has four aspheric lenses for correcting aberrations, distortions, and astigmatism, plus two UD elements and one Super UD element for reducing chromatic aberration.

Lens Coatings: The front and rear lens surfaces are coated with non-stick fluorine to help reduce smears and fingerprints. This helps prevents dust, water, oil, and other surface residue from sticking to the lens, and allows you to quickly and easily wipe the lens clean without the use of solvents. In addition, Air Sphere Coating (ASC) on the lens elements help to combat flare, ghosting, and reflections with reduced aberrations.

12-pin Communication: The Canon RF-series lenses feature a 12-pin communication system between the camera and the lens (compared to 8 pins for the EF-series). This 12-pin system is the fastest available for a Canon lens and camera combination, and provides faster AF, Image Stabilization, Digital Lens Optimizer, and more. In addition, the EOS R camera can display lens information directly to the viewfinder, making it easy to confirm the lens' focal length without looking away from your subject.

Control Ring: The RF-series lenses feature a control ring on the lens barrel, which can be assigned to functions that are commonly used on the camera. These functions include shutter speed and aperture settings, or exposure compensation. The ring has a clicking mechanism that acts as a confirmation that the settings are being changed.

Note: The clicking sound could possibly be picked up by the microphone while shooting movies. If you desire a silent control ring, the clicking mechanism can be removed by a Canon service provider (for a fee).

Focusing Ring: Regardless of whether the lens is set to manual or auto focus mode, the focusing ring always works. This means you can auto focus on a subject, but manually fine-tune the focus by turning the focusing ring.

Lens Hood: The included EW-103 lens hood can keep unwanted light out of the lens, and protect the lens from rain, snow, and dust. You can reverse-mount the lens hood on the lens for storage. Mounting the lens hood adds approximately 1-3/4" to the overall length of the lens.

Optional Filters: The RF 28-70mm lens has a 95mm mounting thread on the front of the lens for attaching screw-on type filters.
