Canon RF28-70mm F2 L USM

A unique full-frame zoom with a constant f/2 aperture

Released in December 2018, the Canon RF28-70mm F2 L USM is a professional L-series standard zoom created for full-frame Canon RF-mount cameras. Canon introduced it as the world’s first full-frame autofocus standard zoom to maintain an f/2 maximum aperture throughout the entire zoom range. Covering wide, normal and short-telephoto perspectives, it is designed for productions that want prime-lens-like brightness without changing lenses between shots. The constant f/2 aperture is especially useful for interviews, portraits, events, music videos and low-light work where shallow depth of field and consistent exposure are important.

Fast USM autofocus without optical stabilization

The lens uses Canon’s USM autofocus system with full-time manual focus override, providing fast and precise focusing for stills and video. Unlike many other RF zooms, the RF28-70mm F2 L USM does not include optical image stabilization. When used on newer EOS R bodies with in-body stabilization, stabilization is provided by the camera rather than the lens. This makes the lens best suited to controlled handheld work, shoulder rigs, tripods, monopods and larger gimbals where its substantial size and weight can be properly supported.

High-end optics for demanding image quality

The optical design uses 19 elements in 13 groups, including multiple aspherical elements, a Super UD element and two UD elements to control distortion, chromatic aberration and loss of sharpness across the zoom range. Canon’s Air Sphere Coating helps reduce flare and ghosting when shooting toward strong light sources. The lens focuses down to 0.39 m and offers a maximum magnification of 0.18x. Its large 95 mm filter thread accepts professional ND, diffusion and polarizing filters suitable for cinema and commercial work.

Heavy-duty L-series construction

At approximately 1.43 kg, the RF28-70mm F2 L USM is significantly heavier than a conventional 24–70mm f/2.8 zoom, but the extra size supports the unusually bright f/2 design. Dust- and water-resistant construction, fluorine coatings and vibration-shock resistance make it suitable for regular professional use. Because of the weight, good lens support and careful gimbal balancing are recommended for longer setups.
