The RF 400mm f/2.8 L IS USM Lens by Canon mirrors the optical characteristics of its EF predecessor, the super telephoto EF 400mm f/2.8L IS III USM lens, ensuring exceptional performance tailored for professional photography of sports, wildlife, and more.

Exclusively designed for EOS R-series cameras, this lens integrates three modes of optical image stabilization, offering up to 5.5 stops of correction for sharp imagery in handheld or monopod-mounted scenarios.

Featuring a circular nine-blade aperture, it achieves exquisite bokeh even at smaller apertures, while advanced Super Spectra and Air Sphere Coatings effectively minimize ghosting and flare, ensuring clear results in challenging backlit conditions.

Incorporating Super UD and fluorite elements in its optical makeup, the lens effectively reduces chromatic aberrations and color fringing, maintaining high clarity and color fidelity.

It includes two customizable focus presets for quick access to predefined focus distances and an electronic focus ring that supports manual adjustments during SERVO AF operation.

Compatible with Canon RF 1.4x and 2x Extenders, the lens boasts a robust, weather-sealed construction with a fluorine coating on the front element for easy maintenance and durability against dust and moisture.
