Canon RF 800mm f/5.6 L IS USM Lens in More Detail
Harness the power of the EOS R system
With their super telephoto capabilities and light weight, the super telephoto prime is the perfect companion for the EOS R3 for sports photography. Working in tandem with the camera’s AF system, the RF 800mm F5.6L keeps track of subjects at up to 30fps. With a Ring USM Drive, Dual Power Drive, high-speed CPU and optimised AF algorithm, the lens provides fast, yet quiet autofocusing, ideal for capturing fast moving wildlife and video. The customisable AF stop buttons on the lens also give photographers enhanced control when focusing on subjects. As part of the RF lens range, photographers receive the added benefit of being able to use the same accessories across the range, including filters and hoods, for enhanced flexibility.
Push performance limits
The RF 800mm F5.6L IS USM is built to get results combining a fast f/5.6 aperture with 4.5-stop Image Stabiliser. Fluorite, UD and Super UD lens elements with advanced coatings, have allowed Canon to design a lens which sets new standards in optical excellence.
Confident control
This is Canon’s shortest and lightest 800mm L-series lens ever made thanks to the inclusion of an advanced optical design. Optimised weight distribution inspires confidence in the user, while full-time manual focus is always available for precise AF control.
Tough and responsive
A highly favoured L-series design puts the priority on usability, with a lightweight magnesium alloy casing with heat insulating paint which protects optics while dust and moisture is repelled by Fluorine on the outer elements.
Built for EOS R
The RF 800mm F5.6L IS USM sits at the top of the Canon lens range together with the Canon RF 1200mm f/8 L IS USM Lens released at the same time. An aperture mechanism with 1/8th stop increments and a minimum focus distance of just 2.6m bring superior flexibility, while the IS system works with in-body IS for even better stability.
Take control
The RF 800mm F5.6L has a host of custom options along with two focus pre-sets and a customisable AF stop button. It is also fully compatible with RF extenders and focus direction can even be reversed to match your workflow.

Our Verdict
With a super telephoto lens of this nature available Canon mirrorless users who shoot distant subjects will be wringing their hands with glee. Not only does the 800mm prime perform at the very highest level, but it does so as the lightest lens of it’s type ever from Canon. Whilst 3.1kg is no featherweight, it’s seriously impressive for the bright aperture and long focal width on offer.
Canon has ensured full compatibility with their class-leading in-body EOS R stabilisation systems for up to 4.5-stops of anti shake compensation, together with the ability to add Extenders for an incredible 1600mm range.
As an L-series lens, build quality is equally impressive as the high rendering capabilities, and the lens is extremely well balanced, while providing suitable levels of customisation for demanding professional users. Plenty of details such as the 9-bladed aperture and close focus distance ensure versatility together with performance which exceeds expectations.
The RF 800mm f/5.6L is the culmination of decades of optical experience, which is all coming together for the RF system to offer unparalleled performance for its users.
