Outstanding image quality
Even at its maximum f/2.8 aperture, sharpness is exceptional right across the frame with this lens. This is due to the use of Fluorite and Super UD glass plus ASC and Super Spectra coatings.
Fast focusing keeps you sharp
When capturing fast action, the lens focuses quickly and confidently. A dual power focus drive offers faster AF with compatible cameras.
Low light? No problem
The Canon RF 400mm f/2.8L IS USM lens is great in low light, with a large f/2.8 max aperture and an IS system offering 5 stops of protection from camera shake.*
The lightweight 400mm f/2.8 lens for mirrorless cameras is easy to take with you. Full-time MF lets you adjust focus and AF start/stop buttons are intuitive to find.
Built to inspire confidence
With its legendary L-series build quality and heat-reflecting white finish, this is a lens you can use confidently whatever the weather – from rainy football pitches to dusty safari trips.
Dual Power Focus Drive
The Canon RF 400mm f/2.8L IS USM features a dual power focus drive system. This means that the lens mount features a second power connection, so that it can draw more current from compatible camera bodies. This extra power is used to increase the USM speed for faster focusing speeds, letting photographers track faster moving objects and obtain initial focus more quickly.
