Capture the action with the Canon RF 400mm F2.8 L IS USM RF Lens. An RF mount super-telephoto lens that offers a 400mm focal length in a lightweight, portable construction. Its features make it perfect for a variety of photographic applications, including wildlife, sport and action. Offering a fast f/2.8 aperture, optical Image Stabilisation and impressive optical design for incredible low light performance. Take advantage of the fast autofocus system for breath taking, pin sharp images of fast-moving objects.
Impressive Low Light Performance
Even at the maximum f2.8 aperture, this lens will perform impressively well in low light. With the addition of an optical Image Stabilisation system, you benefit from 5.5 stops of protection from camera shake.
Superb Image Quality
Canon have incorporated a single Super UD (Ultra-low Dispersion) glass and two fluorite glass elements to ensure images are consistently sharp with high-contrast. The single Super UD element can do the job of two UD lenses and ensures that chromatic aberrations and colour fringing are significantly reduced. Fluorite glass increases image resolution and contrast for overall clarity.
ASC (Air Sphere Coating) has been applied to the lenses to ensure ghosting and flare is decreased when working in bright light conditions.
Fast Autofocus
Capturing fast action has never been easier. The dual power focus drive offers a faster autofocus so you can use your initiative with confidence. Change between three manual focus speeds so you have rapid control over focus and with full-time manual focus you can quickly adjust for more precision. The addition of autofocus start-stop button are also intuitive to find.
When shooting video, you can store two focus presets for quick recall – saving you time when you need to react fast.
Ready to withstand the elements
As an L-series lens, it has been constructed to withstand the rigours of professional thorough use. Featuring dust and moisture resistance and a heat-reflecting white finish to ensure performance stays consistent whether you’re shooting a football pitch on a rainy day or during a safari trip in Kenya.
This is the lightest 400mm lens available for mirrorless cameras, weighing 2890g, making it more comfortable for you to handle and easy to transport.
