The Canon RF 400mm F2.8L IS USM and RF 600mm F4L IS USM lenses are the perfect choice for wildlife, sports and press photography. With their lightweight design, weather-resistant construction and rich image quality, they deliver exceptional images in the toughest conditions.
Although they share much the same optics, mechanics, electronics and firmware as their EF stablemates (the Canon EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM), the RF versions of these classic lenses have a key advantage: the RF mount itself. With 12 electrical contacts – four more than the EF mount – communication between the camera and the lens is much faster and higher-bandwidth, unlocking a new level of performance.
Motorsports photographer and Canon Ambassador Vladimir Rys recently got to grips with the two RF super-telephoto lenses on a rally car shoot with the Canon EOS R3. Vladimir is no stranger to the EOS R System, as he usually uses a Canon EOS R5 – paired with either a Canon RF 50mm F1.2L USM lens or a Canon RF 85mm F1.2L USM – alongside his Canon EOS-1D X Mark III when covering events.
