The RF 800mm IS STM lens is a super telephoto prime lens with 4-stop image stabilisation and a greater reach than its sister lens, the RF 600mm IS STM. It is perfect for the wildlife enthusiast, and ideal for specialist pursuits such as bird and aviation photography. Lightweight, powerful and compact with excellent image stabilisation for handheld shooting, the Diffractive Optic (DO) design, along with the RF lens mount and a fixed, F11 aperture, helps make it a more compact lens and easier to pack into a travel bag. Designed for Canons Full Frame mirrorless cameras, its RF lens mount offers a faster communication speed than a conventional DSLR. Smooth and silent focusing from the STM motor is a real advantage too, particularly for video. Capture safari, aircraft or travel views and shoot the ultimate frame-filling moments in glorious detail that benefit from creative telephoto compression. Thanks to 4-stop image stabilisation, super sharp telephoto images are possible, and you can achieve great handheld video footage too. Because of the RF mount, an F11 aperture and compact Diffractive Optic design, the lens measures 281.8 mm in length when stored and weighs only 1,260 g. An STM motor allows smooth, quiet AF while a Lens Control Ring gives intuitive control over settings. Pleasing bokeh is achieved thanks to a bladeless, F11 aperture. Now its easy to pack a super telephoto lens in your kitbag with powerful image stabilisation and AF which is available to all enthusiasts who want to travel light.
