Canon RF 800mm f/11 IS STM Lens
Key Features
  • RF-Mount Lens/Full-Frame Format
  • Fixed f/11 Aperture
  • Retractable, Locking Lens Barrel
  • Gapless Dual-Layer Diffractive Optics
Super long reach, super compact design, the Canon RF 800mm f/11 IS STM is a unique telephoto prime featuring a distinct mixture of focal length and form factor. Characterized by its retractable design and a fixed f/11 aperture, this lens's sleek profile makes handheld super-tele shooting a very real possibility, and four stop-effective optical image stabilization further helps to achieve sharp imagery when working in difficult lighting conditions. Also contributing to the reduced size is a distinct optical layout, which uses gapless dual-layer diffractive optics instead of multiple heavier individual elements, which also effectively controls color fringing and chromatic aberrations for high clarity. Complementing this design is an STM stepping motor that delivers quick and quiet autofocus performance that is suitable for both stills and video needs. Additionally, a Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself. If you decide you need more than 800mm, this lens is compatible with the 1.4x and 2x RF Extenders for an equivalent focal length of 1120mm or 1600mm, respectively.

Canon RF 800mm f/11 IS STM Overview

By B&H Photo's

Super long reach, super compact design, the Canon RF 800mm f/11 IS STM is a unique telephoto prime featuring a distinct mixture of focal length and form factor. Characterized by its retractable design and a fixed f/11 aperture, this lens's sleek profile makes handheld super-tele shooting a very real possibility, and four stop-effective optical image stabilization further helps to achieve sharp imagery when working in difficult lighting conditions. Also contributing to the reduced size is a distinct optical layout, which uses gapless dual-layer diffractive optics instead of multiple heavier individual elements, which also effectively controls color fringing and chromatic aberrations for high clarity. Complementing this design is an STM stepping motor that delivers quick and quiet autofocus performance that is suitable for both stills and video needs. Additionally, a Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself. If you decide you need more than 800mm, this lens is compatible with the 1.4x and 2x RF Extenders for an equivalent focal length of 1120mm or 1600mm, respectively.

Super-telephoto prime is designed for use with full-frame Canon RF-mount mirrorless digital cameras.
Fixed f/11 aperture contributes to the sleek and portable form factor as well as a balanced mixture of depth of field and sharpness.
Gapless dual-layer diffractive optics contribute to a marked reduction in chromatic and spherical aberrations as well as benefit the design of a relatively compact and lightweight lens.
Retractable/extendable design, with a locking lens barrel, offers an impressively compact form factor considering the super-telephoto design.
An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four stops to better enable working in low-light conditions and with slower shutter speeds.
STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting.
Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.

Canon RF 800mm f/11 IS STM Reviews

Great reach at a reasonable cost

By Robert
Rated 5 out of 5

Works pretty well once you get used to a smaller focus area and an F11 aperture.

it is lightweight but hardly use

I need to try to use more often since it has such good range.

Excellent lens

For a beginner of bird photography it's a nice lens in my opinion, I'm aware also that I cannot compare this lens to an expensive one ($12,000)

First Ever 800mm

By Carrie
Rated 4 out of 5
Date: 2022-04-17

This lens is the first 800mm I've ever owned and I'm very happy with it so far. You definitely need very good light to get decent shots but when you have that, this lens can be amazing. I can't afford the other primes so I can't be too picky. Taking one star off because the minimum focus distance is insanely far.

Nothing to Sneeze at

Canon sent me a copy of this lens to test out. I own the EF800mm, EF600/4, EF 200-400/4.5-5.6, so I'm pretty critical when it comes to image quality and sharpness. I have to confess that I was prepared to be underwhelmed by this new 800mm, but I was anything but. Sure it has the limitations of a fixed aperture, but for a lens costing roughly what the sales tax is on any of the aforementioned lenses, it's a very good product. I shot it side by side on my R5's with the 200-400 and, in the lighting conditions of the day, one would be hard pressed to differentiate between the two lenses.

Very Good Value

I have owned the 800mm for about a month and use it on my R5. I rated it as a 4. I like the reach, weight, and price. The IQ is good if you have a lot of light and you use Topaz Denoise.

I love this lens!

By Connie A

I finally have the reach to capture all the birds and critters that I love without having to sell my car! Now, it does need a lot of light, but paired with the R6 I've had no problems. The photos shown are after only a few days playing with it. The animal eye tracking is phenomenal between the two. I'm very please with it.

Great value

Great lens for the money. I only wish it was a little lighter even though it's very lite for the size. I can definitely get photos that I normally could not previously because of the extra reach.

Does it come with a hood or foot/tripod mount?
Asked by: Steve
I dont know that I would call it a foot like on other long Canon lenses but there is a mounting pad on the bottom of the lens, located just below the stabilizer switch. It is configured just like a standard camcorder mount with a -20 tapped hole plus a non-tapped hole that mates to an anti-rotation pin. I happened to have an old RRS B26 ARCA-Swiss QR plate with the camcorder pin on it, and this mates perfectly to the bottom of the lens so you can mount it to any ARCA-Swiss tripod head. Worked great for me.

Asked by: Anonymous
It has an RF mount. You can buy an adapter that will allow the RF mount to fit any Canon camera with an EF mount. So with an adapter it will fit, however with the crop factor of an APS-C lens, the field of view will be more like 1200-1300mm.
