The Canon RF 28-70mm f/2.8 IS STM is an RF-mount, full-frame, midrange zoom equipped with optics that rival Canon’s L-series lenses. Key features include:
Up to 5.5 stops of optical image stabilization
Leadscrew-type stepping motor for fast, quiet autofocus
Minimal focus breathing when recording video
L-series optics in a smaller, more affordable form factor
Canon RF Mount. The Canon RF 28-70mm f/2.8 IS STM belongs to Canon’s advanced EOS R line, which offers a wide-diameter mount that allows RF lenses to sit close to an EOS R sensor for reduced aberrations, increased sharpness, and better light-gathering abilities. Extra pins inside this camera line’s mount produces fast communication between camera and lens, which benefits rapid and efficient autofocus.
Versatile Midrange Zoom. This lens’s wide-to-short-telephoto zoom range is ideal for everyday shooting. It maintains a much smaller form factor when compared to an L-series Canon RF 24-70mm f/2.8L IS while maintaining image stabilization and an f/2.8 maximum aperture throughout the entire zoom range.
Features that Benefit Videographers. With a fast stepper (STM) autofocus motor, controlled focus breathing, and a smooth manual focus ring, the Canon RF 28-70mm f/2.8 IS STM is a great, portable option for vlogging, b-footage, and events.
Advanced Optics. Image stabilization got an overhaul with this lens for a lighter and smaller overall build. Dual ultra-low dispersion (UD) elements, along with dual glass-molded aspherical lenses, correct for aberrations while the Super Spectra Coating (SSC) maintains good light transmission and high contrast.
Configurable Control Ring. Take exposure control into your hands, literally, with the Canon RF 28-70mm f/2.8’s on-barrel control ring. This click-stopped ring can be customized to a setting of your choice: shutter speed, aperture, ISO, and exposure compensation. This can be changed in the Custom Functions menu of an EOS R-series camera. This is a great feature for settings you access most frequently.
Try it with These RF-Mount Cameras. The portable nature of this lens makes it a great option for shooters on the go and pairs well with slightly more compact cameras like the Canon EOS R8 and the Canon EOS RP. However, this full-frame lens can be used with any EOS R-series, RF-mount camera. On a cropped-sensor (APS-C) EOS R camera, the Canon RF 28-70mm f/2.8 IS STM produces an effective range of approximately 45-112mm.
