The maximum magnification of 0.41x at the telephoto end also allows you to shoot beautiful close-up tele-macro shots, further extending the versatility of this zoom.
Sharp and extremely stable
The powerful 5.5-stop Optical Image Stabilisation gives the RF 100-400mm F5.6-8 lens a solid advantage for getting sharp handheld stills and smooth movies. It can also work in tandem with compatible EOS R cameras for an additional 0.5 stops of stabilisation.

Weighing just 635g and measuring 164.7mm in length this compact, lightweight lens will be well balanced on any camera, even when fully extended. At this compact size it also fits in a kit bag remarkably well so you can bring it on your adventures.
Responsive performance with smooth and fast AF
The Nano USM motor focus is fast, quiet and smooth, making use of Canon’s advanced Dual Pixel CMOS AF, while a Lens Control Ring gives added control over settings. A nine-blade aperture delivers great background blur allowing you to isolate your subject beautifully against the background.
Super telephoto range
The RF 100-400MM F5.6-8 IS USM is a great choice for animal photography and other distant subjects, producing great results thanks to Ultra-low Dispersion (UD) glass and advanced optical coatings.

The Canon Extender RF 1.4x extends the focal range to 140mm - 560mm with an aperture range of f/8 - f/11 while the Canon Extender RF 2x doubles the range to 200mm - 800mm with aperture range of f/11 - f/16.

The number of RF lenses is swelling rapidly as this RF 100-400mm f/5.6-8 IS USM joins the line-up at the same time as the RF 16mm f/2.8 STM Lens. Canon has given us one of the lightest and most compact telephoto zooms with the RF 100-400mm, which offers a greater degree of versatility over prime telephoto lenses like the RF 600mm f/11. The 9-bladed aperture is bright enough for most situations and the lens works seamlessly with RF Extenders for even greater reach with full AF functionality.
Optical stabilisation gives you an impressive 5.5 stops of advantage, which helps considerably when handholding, virtually eliminating the need for a tripod or monopod in many instances. This in turn keeps weight down as this lens is all about lightweight portability for wildlife, sports and family adventures. You get a control ring on the lens barrel, which can be set to your workflow, along with good quality optics and lens coatings for great image and video quality. AF is fast, quiet and responsive allowing you to keep up with your subjects and a close minimum focus distance lets you capture frame-filling tele-macro subjects.
There’s like a lot to like about the RF 100-400mm which is considerably cheaper than its nearest stablemate, the RF 100-500mm L IS USM and it’s super lightweight offering great results throughout the range.
