Setting new standards – a fast, versatile, ultra high-quality zoom for the Canon EOS R System.

Redefining what can be expected of a standard zoom lens, the RF 28-70mm f/2 L USM features a fast f/2 aperture and delivers new levels of image quality.

Redefine what you expect from a standard zoom lens

The performance of the RF 28-70mm f/2 L USM is nothing short of extraordinary, thanks to the Canon RF mount, which allows previously impossible optical designs to now be realised. The lens uses four aspherical elements, a pair of Ultra low Dispersion (UD) elements and a Super UD element to deliver the optical quality normally expected of a prime lens. It’s versatile too, with a zoom range that will find uses in just about every area of photography.

Super-fast f/2 maximum aperture for extra creative power

An f/2 maximum aperture gives photographers huge control over depth of field – perfect for portrait and wedding photographers looking to isolate a pin-sharp subject against a smooth out-of-focus background. Such a large aperture also allows for faster shutter speeds when shooting in low-light, which can freeze both subject movement and camera shake.

Smooth, near-silent autofocusing, with Canon’s USM technology

The RF 28-70mm f/2 L USM borrows the ring-type USM technology from Canon’s super-telephoto lenses in order to move its large glass elements quickly and in near silence. In combination with the fast data transfer allowed by the RF mount, this technology lets photographers focus fast. And tracking moving subjects with ease.

Smart controls and intuitive ergonomics for a natural shooting experience

A customisable Control Ring on the lens’s barrel lets photographers adjust settings quickly and easily without taking their eye away from the camera. This tactile, intuitive device can be programmed to perform various functions such as aperture, shutter speed and ISO adjustment, and exposure compensation.

Legendary Canon L-Series pedigree inspires confidence

As an L-Series lens, the RF 28-70mm f/2 L USM is built to exacting standards and designed to withstand the rigors of professional use. Plus, it’s sealed against dust and moisture, so bad weather and harsh conditions won’t interrupt your creativity.
