Canon RF 400mm f/2.8L IS USM Lens
Optically identical to the super telephoto EF 400mm f/2.8L IS III USM lens, the RF 400mm f/2.8L 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. This level of stabilization ensures that your images remain crisp and clear, even in challenging shooting conditions, such as low light or fast-moving subjects.
A circular nine-blade aperture provides beautiful bokeh at smaller lens apertures, creating a smooth and pleasing background blur that makes your subject stand out. This is particularly beneficial for portrait and wildlife photographers who want to isolate their subjects from the background. Super Spectra and Air Sphere Coatings minimize ghosting and flare for exceptionally clear results when shooting in backlit situations, ensuring that your images have high contrast and vivid colors.
Additionally, Super UD (Ultra-low Dispersion) and fluorite elements used in the optical design reduce color fringing and chromatic aberrations for high clarity and color accuracy. This sophisticated optical construction ensures that your images are sharp from edge to edge, with minimal distortion and excellent color reproduction. Two focus presets allow you to instantly return to one or two memorized focus distances, which is a valuable feature for sports and wildlife photographers who need to react quickly to changing scenes.
A customizable electronic focus ring allows manual focusing during SERVO AF, providing greater control and precision when you need it. The RF 400mm f/2.8L IS USM Lens is also compatible with Canon RF 1.4x and 2x Extenders, extending its reach to 560mm or 800mm, respectively. This versatility makes it an excellent choice for photographers who need to capture distant subjects without sacrificing image quality.
The lens incorporates a dust and water-resistant design, ensuring reliable performance in various weather conditions. The robust construction is complemented by a fluorine coating on the front element for easy cleaning, protecting the lens from dirt, smudges, and moisture. This durability and ease of maintenance make the RF 400mm f/2.8L IS USM Lens a dependable tool for professional photographers working in the field.
In terms of handling, the RF 400mm f/2.8L IS USM Lens is designed to be user-friendly and intuitive. Its ergonomic design and balanced weight distribution make it comfortable to use for extended periods, whether you are hand-holding the lens or using it on a tripod or monopod. The lens’s fast and quiet autofocus system ensures that you can capture decisive moments with minimal delay, while the focus limiter switch allows you to narrow the focusing range for even faster performance.
The lens’s advanced optical and stabilization technologies, combined with its rugged build quality, make it an ideal choice for professional photographers who demand the highest level of performance from their equipment. Whether you are photographing a fast-paced sports event, a serene wildlife scene, or any other challenging subject, the RF 400mm f/2.8L IS USM Lens delivers exceptional image quality and reliability.
