Canon RF 100-400mm F5.6-8 IS USM 


Capture distant wildlife, sports and family adventures with this lightweight, compact 100-400mm RF-series zoom. With an advanced 5.5-stop Image Stabilizer2, great close focusing capability plus the powerful reach of a telephoto, it’s a stunning affordable lens that will bring those important moments to you.



Reach those distant subjects with ease

The RF 100-400MM F5.6-8 IS USM’s zoom range gives you the power and flexibility to capture a subject both close1 and even far away. It’s ideal for sports photography, wildlife or a day trip to the park.


Super sharp and highly stable

Powerful 5.5-stop Optical Image Stabilisation2 gives the RF 100-400MM F5.6-8 IS USM a great advantage for achieving sharp handheld stills and smooth movies with no need for a tripod to weigh you down.


Revolutionary size and weight

Weighing just 635g and measuring 164.7mm in length, this compact, lightweight lens is well balanced, even when fully extended, and fits in a kit bag beautifully.


Responsive performance with smooth, fast AF

Thanks to a Nano USM motor focusing3 is fast, quiet and smooth, while the Lens Control Ring gives control over settings. A nine-blade aperture delivers great background blur, too.


Super telephoto power

The RF 100-400MM F5.6-8 IS USM is ideal for animal photography and distant subjects producing great results thanks to Ultra-low Dispersion (UD) glass and advanced coatings.


Extend your reach even further

Increase your telephoto power with Canon RF extenders, which connect seamlessly4 with metering and Auto Focus to give you even greater precise reach for those faraway subjects.

"In preparation for an upcoming safari this was purchased as an alternative to a very heavy Sigma 150 - 600mm. Based on a few test runs so far I have to say I'm not disappointed. A third of the weight means hand holding isn't a problem and image stabilisation allows quality shots even in low light. The excellent finance deal and very prompt delivery by Castle Cameras have convinced me I've made the right choice, with the right people."

"The Canon RF 100-400mm is a lightweight and compact lens that focuses quickly and quietly, has good image stabilisation and excellent image quality. This lens is shorter and lighter than my old EF 70-200mm but seems to focus just as well and obviously has twice the “reach”. I took the 100-400mm to the zoo and was very happy with the handling, performance and image quality. The slow maximum aperture was not an issue for me and coming from APS-C I found the background separation was still good. And the R-series cameras have no problems auto-focussing at f8. A great and (relatively) affordable addition to the RF lens lineup. Pair with a 24-105mm f4-7.1 and you have a very versatile setup that weighs less than 2kg (inc. body). "
