Canon RF 400mm f/2.8L IS USM Lens Summary
The arrival of the Canon RF 400mm f/2.8L IS USM Lens marks a new era of professional native super telephoto lenses for the full frame Canon mirrorless system. A combination of Fluorite and Super UD glass elements with ASC and Super Spectra coatings result in superb image quality, which will satisfy professional and enthusiast wildlife, sports and action photographers. The lens focuses quickly, quietly and confidently, even with faster moving subjects as it is assisted by a Dual Power Focus Drive, which draws extra power from any compatible camera body.
Photographers working in low light benefit from a large, bright f/2.8 aperture together with image stabilisation (IS) for up to 5 stops of compensation. Hand holding is more comfortable with the RF 400mm f/2.8L IS USM lens as it weighs just 2890g, which is the lightest professional 400mm lens available for any mirrorless system at the time of launch.

Canon has thought about versatility of the RF 400mm f/2.8L with full-time MF letting you adjust focus as well as AF start/stop buttons which are intuitively placed on the lens barrel. Even the 2.5m close focus distance provides greater flexibility for subjects nearing the photographer.
Canon RF 400mm f/2.8L IS USM Lens in More Detail
Advanced AF Capability
Advanced AF keeps any erratic and fast-moving subjects pin sharp, assisted by a dual power focus drive which delivers faster AF with compatible cameras. Full time MF is also on hand to fine tune focus without the need for toggling an AF switch.
Exceptional image quality
Canon has integrated Fluorite and Super UD glass elements into the optical design with ASC and Super Spectra coatings resulting in clear, sharp images right across the frame, even when shooting into lights.
Low light performance
The RF 400mm lens is extremely competent in low light with a large f/2.8 aperture and an image stabilisation system with 5 stops of shake compensation. Add in the fact this is the lightest pro 400mm super telephoto prime for full frame mirrorless systems and users can achieve excellent results even when hand holding as light dips.
Durable build quality
This is a lens to use whatever the weather in any situation indoors or out, as it has been designed with legendary L-series build quality and signature heat-reflecting white finish.
Dual Power Focus Drive
The RF 400mm f/2.8L mount features a second power connection referred to as a dual power focus drive system, allowing the lens to draw more current from compatible camera bodies. This extra power is used to increase the USM speed for faster focusing, letting photographers obtain initial focus more quickly and track moving objects effortlessly.

Our Verdict
At the time of release the Canon RF 400mm f/2.8L IS USM Lens is the lightest mirrorless 400mm lens in its class. This is significant for Canon photographers as they will be able to hand hold for longer periods when capturing beautiful wildlife, sports and action photos. Lighting conditions can be challenging for all of these subjects, but users have not only the bright f/2.8 aperture to fall back on, but also up to 5 stops of image stabilisation.
Fast moving subjects can also acquired and tracked with confidence thanks to the dual power focus drive which employs clever technology to draw extra power directly from the camera body when needed. This results in faster AF particularly when combined with Canon’s outstanding Dual Pixel Autofocus system. A full time MF override is also available for fine tuning without the need to flick any switches, along with well thought out AF start/stop buttons.
With the delayed Olympics and Euro 2020 just around the corner, pro sports photographers will definitely be eyeing up this and the RF 600mm f/4L IS USM Lens with keen interest. We also expect photographers who love outstanding imaging results for wildlife or action to consider this model as the definitive, weather sealed, professional L-Series super telephoto prime in its class.
