The Canon RF 400mm F2.8 L IS USM – photographic lens lets you get right in the heart of the action, whether you’re photographing a sporting event, wildlife on safari or shooting news events. This RF mount super telephoto lens, designed for the EOS R series of cameras, offers outstanding image quality and performance. A maximum aperture of f/2.8 offers shallow depth of field and exceptional low-light performance, all complemented by a 5.5 stop image stabiliser. The robust construction of the L-series allows you to continue shooting even in adverse conditions. Focusing is lightning-fast, thanks to the ring-type USM motor and dual-feed focus motor, which increases AF speed in compatible cameras. Continuous manual focusing allows you to make small corrections without taking your eyes off your subject.
