Canon RF 400mm f/2.8 L IS USM Lens
Key Features
  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/2.8 to f/32
  • Optical Image Stabilizer
  • Super UD and Fluorite Elements
Optically identical to the super telephoto EF 400mm f/2.8L IS III USM lens, the RF 400mm f/2.8 L IS USM Lens from Canon delivers high-performance results and is a go-to choice for capturing professional-quality shots of sports, wildlife, and more. Designed exclusively for EOS R-series cameras, the lens features three modes of optical image stabilization with up to 5.5 stops of shake correction to deliver extremely sharp results whether hand-held or mounted on a monopod. A circular nine-blade aperture provides beautiful bokeh at smaller lens apertures, and Super Spectra and Air Sphere Coatings minimize ghosting and flare for exceptionally clear results when shooting in backlit situations. Additionally, Super UD and fluorite elements used in the optical design reduce color fringing and chromatic aberrations for high clarity and color accuracy. Two focus presets allow you to instantly return to one or two memorized focus distances, and a customizable electronic focus ring allows manual focusing during SERVO AF. The RF 400mm f/2.8 L IS USM lens is also compatible with Canon RF 1.4x and 2x Extenders, and the lens incorporates a dust and water-resistant design with a fluorine coating on the front element for easy cleaning.

How does this lens perform (effect on IQ) with the 1.4 and 2 TCs?
Asked by: Steven
When using the Canon RF 400mm f/2.8 L IS USM Lens wide open with the Canon Extender RF 1.4x, image sharpness is decreased modestly in the center in the center of the frame, but corners are nearly unaffected. Stopping down one stop brings a nice improvement and impressive sharpness across the frame. The RF 1.4x adds a slight barrel distortion but notably does not affect lateral CA. The results are a bit soft when using the Canon Extender RF 2x on the RF 400mm f/2.8. The sharpness is good across the frame if you stop down one stop. The 2x Extender increases lateral CA noticeably and barrel distortion slightly. The 2x Extender does impact sharpness and contrast.
