Canon RF 800mm f/11 IS STM Lens

The Canon RF 800mm f/11 IS STM is a super-telephoto lens ideal for bird, wildlife, outdoor sports, and aviation photography, or scenario where you just want to bring your subject closer. With an impressive 800mm focal length and STM focusing system quickly and quietly focus and track your elusive subjects out in nature. The Canon RF 800mm f/11 IS STM lens comes with built-in optical image stabilization system with up to 4 stops of shake correction that allows for comfortable hand-held shooting or shooting with a monopod. When used with optional RF 1.4x or 2.0x teleconverters, this super-telephoto lens’ focal length can be increased to an astonishing 1120mm or 1600mm range respectively.

Compact and Lightweight Telephoto RF Lens

Thanks to a compact design, the RF 800mm f/11 IS STM Super-Telephoto Lens is more portable than its EF counterparts in this category. The lens uses gapless dual-layered diffractive optical elements that help reduce chromatic aberration to achieve clear images with minimal to no color fringing, even at a fixed aperture of f/11. This means detailed results of landscapes and more, even from a distance. Plus, only one DO lens has the optical characteristics of multiple lenses, reducing the count of elements and thus contributing to the lens’ lightweight construction.

Lead Screw-Type STM Enables Smooth Autofocusing

This RF 800mm f/11 Super-Telephoto Lens incorporates a lead screw-type STM focus motor that helps achieve smooth and quiet autofocus whether you're capturing stills or tracking a subject while recording videos. The virtually near-silent operation is ideal when you’re shooting in environments where silence is extremely important like especially when capturing wildlife. The STM motor significantly reduces the chance of your subject being disturbed.

Optical Image Stabilization

Steady and clear images are difficult to achieve especially when shooting with a super-telephoto lens. Thanks to the built-in powerful optical image stabilization with up to 4 stops of shake correction, the RF800mm Lens gives you more confidence. It significantly helps reduce camera shake whether you’re shooting handheld or with a monopod

Locking Lens Barrel Design

A retractable lens barrel when not shooting contributes to the lens’ compact design for easy handling during transportation. When you're ready to shoot, just unlock to extend the lens barrel, lock it in place for stability and capture your shots.

Control Ring for Direct Setting Changes

Like all RF lenses, the RF 800mm lens also comes with a customizable control ring that is easily accessible for settings like shutter speed, aperture and ISO while still looking through the viewfinder.

Canon RF 800mm f/11 IS STM Lens

Canon RF 800mm f/11 IS STM Lens SKU: 3987C002

Rated 5 out of 5 by from 800mm oh yeah. Great lens and cheap for its length but requires practice to find targets quickly.

Rated 4 out of 5 by from it ok if starting photography its a great lens to learn on for bird watching and astrophotography. its a lens that's good at a lot of things but not great at anything. It fixed f11 really hinders it from being perfect.

Rated 4 out of 5 by from Nice lens if you use it under the right conditions All things considered, I do like this lens. As with every piece of equipment, you need to know when and how to use it to get the best results. At first, I have to admit I wasn't impressed with this lens. But I was in a hurry the other day and didn't have the time or patience to take out my "real" 800, so I grabbed this one and, as things turned out, the pictures were amazing. Yes, you need really good light and have to know how to manage your shutter speed and ISO to accommodate the fixed f/11. But all that notwithstanding, the lens itself does what its supposed to do, and at less than 1/10 the cost of something better and bulkier. I'm glad I have this one1

Rated 5 out of 5 by from All doubts erased… I am no longer an f-stop snob! I bought this lens refurbished from this Canon website for my new Canon R8. Active in bird photography, I wanted something to complement my EF 80-200mm IS L II with a 1.4x adapter. The EF zoom is outstanding, but 280mm from this lens/adapter combo just can’t get me close enough to the wildlife. The 800mm is shockingly light compared to my EF lens, and when I use the R8’s 1.6 crop option… I am able to get 1280mm from this setup. I’ve never used anything beyond 600mm in the past, so this lens allows me to obtain clear shots from very long distances. The stabilization with up to 4 stops works very well, as I primarily use this lens hand-held. I just set my shutter to 1000 to ensure the lens does not pickup my movement. Yes, with an f11, this lens is relegated to sunny days. The only other issue I encounter is the long minimum focusing distance (about 19 feet). I missed a few shots of birds landing closer to me; however, I realize this lens’ purpose… extreme long distance photography. In this capacity, this 800mm lens does an outstanding job!

Rated 3 out of 5 by from Depends on what camera you use Tested this lens under different conditions, as expected low light and birds in flight were rather difficult. So my final test was done with an R7 and the RF800 f11. my best results were with bright early morning sunlight, however there are some concerns about the focus "abilities" of this lens. I've added a few screen shots of the pictures in Digital Photo Professional software that shows the focus point. The camera did go to the eye but the focus is actually about 1 to 2 feet in front of the bird...pictures speak for themselves.

Rated 5 out of 5 by from Great lens for the money I've only used it to take shots of the moon so far but I'm happy with the results!
Date published: 2022-11-16
Rated 5 out of 5 by from Reliable lens on my Canon R6 and Canon RP. Purchased from the Canon Store. Owned it for a year now and have achieved good results when used under the right conditions. Works well for surfer shots from the beach. Light enough for hand held use,but I like it setup on a monopod or tripod.

Rated 2 out of 5 by from Buyer's remorse Like others said, the AF randomly stops working. This 100% kills this lens for me. I have gotten decent photos but I simply don’t trust it- like at all. I originally had it paired with the RP body and thought it was the AF in the body causing issues, so I upgraded to the R6 and the problem is still there. I also have failed to get the AF to work at the 20’ mark. I really wish I didn’t buy this and sadly wouldn't recommend it to anyone, even for the price.
