Canon RF800mm F11 IS STM Lens

MFR SKU: 3987C002 | Helix SKU: CA3987C002

Overview

The RF800mm F11 IS STM super-telephoto lens provides a long 800 millimeter focal length and is the first compact and lightweight 800mm super telephoto lens in the RF lineup. This lens is ideal for bird, wildlife, outdoor sports, and aviation photography or, when you just want to bring those subjects in the distance closer to you. The RF800mm F11 IS STM lens features an STM focusing system ideal for fast and quiet focusing when tracking elusive subjects out in nature.  Additionally, an optical image stabilization system with up to 4 stops of shake correction* makes it easy to use either hand-held or with a monopod. It will also accept an RF 1.4X or 2.0X teleconverter^ to increase your focal length to a staggering 1120mm or 1600mm respectively. 

First Compact and Lightweight 800mm Super Telephoto RF Lens


The RF800mm F11 IS STM Lens is the first 800mm super-telephoto in the RF lens lineup and is more portable than its EF counterparts in this category because of its design advantage. The 800mm range provides a far reach not only in distance to the subject, but also in terms of who can utilize with its affordable price, smaller super-telephoto footprint, and lighter weight.


Excellent Portability made Easier with an Extending/Retracting Locking Lens Barrel Design.


With a design that enables you to retract the lens barrel when not shooting, the lens is even more compact so it can more easily be stored or carried in a bag with additional lenses and accessories. When you’re ready to shoot, just unlock to extend the lens barrel, lock it in place for stability and capture your shots, then unlock, retract, and store again to easily move to your next destination.



Gapless double-layer Diffractive Optics (DO) reduce Chromatic Aberration for High Image Quality


The use of gapless dual-layered diffractive optical elements helps reduce chromatic aberrations so your images are clear and detailed for high-quality results all around. And because one DO lens has the optical characteristics of multiple lenses, this contributes to the lightweight of the lens itself, as well.

High Image Quality at a fixed f/11 Aperture.


Impressive results are always the goal and with the RF800mm lens and its use of diffractive optic elements, chromatic aberration can be virtually cancelled out to achieve clear images with minimal to no color fringing, even at a fixed aperture of F11. This means detailed results of landscapes and more, even from a distance.

Optical Image Stabilization with up to 4 Stops* of Shake Correction.


Steady and clear images aren’t always the easiest to come by, especially when shooting with a super-telephoto lens, but with the powerful image stabilization function in the RF800mm, you can feel far more confident it won’t be an issue. Whether shooting handheld or with a monopod, the built-in IS with up to 4 stops* of shake correction helps to significantly reduce camera shake to stabilize the image and get you the results you want and need.

Lead Screw-type STM enables Smooth Autofocusing for Still-image and Video Shooting.


The use of a lead screw-type STM focus motor means smooth and quiet autofocus can be achieved whether you’re shooting stills or tracking a subject while shooting video. While it’s nice to be near-silent anyway, it’s especially important in instances where you’re trying to capture the flight of a wild bird or the relaxation of a wild animal. With the STM feature of the RF800mm, you can capture the scene while significantly reducing the chance of the subject being disturbed.

Control Ring for Direct Setting Changes.


Like all RF lenses before it, the RF800mm lens comes with a customizable and easily accessible control ring so you can change settings like shutter speed, aperture and ISOwhile still looking through the viewfinder.

12-pin Communication System.


A 12 pin connection between your EOS R series camera and the lens means communication at a higher speed with larger amounts of data transfer, enabling incredibly fast Autofocus calculations, impressive image stabilization and even Control Ring adjustments.

Compatible with RF1.4x/RF2x Extenders for 1120mm/1600mm


If 800mm isn’t far-reaching enough, the RF800mm lens is compatible with both the RF Extender 1.4x and RF Extender 2x to help get you even closer, up to 1120mm with the 1.4x or 1600mm using the 2x. This added flexibility and versatility helps make the RF800mm an amazing option for your landscape, wildlife, sports photography and more.

Functional, Look Great
Color: Brown
These were nice corner shelves that were easy to install, and look great. There are plenty of other options on Amazon that offer more shelves and/or at a lower price, but these ones look nicer than most. Overall they're pretty easy to install. It's not exactly a two-person job, but it is easier if you have help - someone to hold the shelf and a level, and the other to mark the holes. My only other recommendation is to check your L-brackets before you do anything. Some come bent inward, some bent outward. If they're really crooked it will make it hard to wedge the shelf into the corner and may result in uneven measurements/holes, so make sure you straighten them out first.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
