Whether you’re shooting action from the touchline, wildlife on safari or news events from the press pack, this RF mount super-telephoto lens puts you right among the action. Since it works natively with EOS R series cameras, it delivers exceptional image quality and performance. An f/2.8 maximum aperture allows shallow depth of field and exceptional low-light performance, which is complimented by a 5.5-stop Image Stabiliser¹. Our robust L-Series construction lets you keep shooting even if conditions turn bad. Focusing is lightning fast, courtesy of a ring-type USM motor and Power Doubled Focus Drive, which increases AF speed with compatible cameras. Full-time manual focus lets photographers make small adjustments without having to take their eye off the subject.


  • Fill the frame from a distance – perfect for sports, wildlife, and news photography. This native RF mount lens is also compatible with RF 1.4x and RF 2x extenders for extra reach
  • A great performer in low light, this lens features a 5.5-stop Image Stabilizer that protects against camera shake¹, plus a fast f/2.8 max aperture, which also allows a very shallow depth of field
  • Outstanding image quality right across the frame, thanks to fluorite and Super UD glass that tackle aberrations and ASC and Super Spectra coatings that reduce ghosting and flare
  • Autofocus is swift and accurate thanks to a ring-type USM motor, enhanced AF algorithms and a Power Doubled Focus Drive that increases focusing speed with compatible cameras
  • The RF 400mm F2.8L IS USM is extremely portable, being a lightweight 400mm f/2.8 lens, weighing in at just 2890g and measuring 367 mm in length, so you can enjoy its extraordinary capabilities wherever you’re shooting
  • Manual focus override allows photographers to make small adjustments to the point of maximum sharpness without having to switch focus modes or taking their eye off the subject
  • A minimum focus distance of just 2.5m means you can keep shooting even when gets close – invaluable when on the touchlines
  • Focus preset buttons allow pre-programmed focus distances to be recalled instantly, saving valuable time when reacting quickly to fast-changing events
  • The RF 400mm F2.8L IS USM is built to exacting standards – sealed against dust and moisture. Its white, thermally reflective paint ensures a stable inside temperature, even in sunlight, for consistent results
