Very light weight and adds little to the length of the lens. We use it with the new Canon 100-400 lens to add an extra 160 mm to the lens. It allows the camera to communicate perfectly with the lens. We have used it only a few times but has allowed us to take wildlife shots.

It restricts the 100-500mm lens to 300-5000 times the 1.4 extender because Canon saved money by narrowing the outer casing so the the extender intrude into the lens stopping it from collapsing pas the 300mm mark. on the ef 1.4 extender the outer housing is longer and this doesn't happen. This means you loose the closeup ability of the lens whewn the extender is attached.

Great addition to my telephoto lens

I use it regularly with my new RF 100-500mm Canon lens with good results. Slightly inconvenient that when in use, I cannot fully retract lens.

Fantastic

I got this for the RF 100-500 lens, and I love it. It really extends that lens's reach. I do not see any IQ loss when using it. The only complaint I have is that I can only use that lens in the 300-500mm range with it on.

Amazing 1.4x Extender!

By Robert W

The Canon Extender RF1.4x is great. It is light weight and when on a lens it actually lengthens the lens less than my old EF version. The image quality of the photos with it seems better than the EF version to me and I never had an issue with the EF 1.4x on my EF 100-400mm L ii. I mainly bought this to use on my new RF 100-400mm in order to extend my range to 560mm. But it also works well on my RF 800mm F11, giving me a whopping 1120mm. So now I have a lighter, smaller zoom with amazing minimal focus distance and over full zoom range for small birds that are close to me and my 800/1120mm for larger birds or birds at more distance. The combination of these three pieces gives me amazing flexibility, less weight and less room in my pack. It's true that at dawn and dusk I've given up some light-gathering ability, but honestly, I don't shoot then most of the time any more. I couldn't be happier with the Extender RF1.4x using my R6. It pretty much stays on my 100-400mm most of the time. It's given me a lot of flexibility for minimal cost and great weight/space savings.

Excellent with RF 100-400 on Canon R5.

The RF 100-400 comes with .41 magnification. Adding this extender boosts that to .57, which is enough to show even small insects. That makes it versatile enough to shoot everything from battling fruit flies and ladybugs preparing for takeoff to great horned owls and preening northern flickers. This combination is almost always on my R5. The attached files, especially of insects, have all been cropped but the sharpness remains. Wish this extender matched more of my RF lenses, but it does very well on the two it does fit.

Okay

will this extender work with an ef to rf adapter?
Asked by: Robin
No, the RF extenders do not work with the EF-RF adapter. The EF-RF adapter doesn't fit over the RF 1.4 or 2.0x teleconverters/extenders. The only way to use a teleconverter with the EF-RF adapters is to use an EF-teleconverter. If you need further clarification or proof, please reach out to our video-chat team and we will be happy to assuage your concerns!

When using rf 100-500 and 1.4x converter, is there any chance of the 1.4x converter touching the back glass of the 100-500 lens (whether when attaching or zooning)?
Asked by: Michael
Yes there is a chance that this extender can touch the rear element, therefore it can only be used within the 300-500mm range on the RF 100-500mm lens.

RF 100-500mm f/4.5-7.1L IS USM (can only be used within 300-500mm range). What does 300-500 range mean? So while on my New R5 (on order) what happens between the 100-300 portion of the zoom?
Asked by: Patrick
When you're using the RF 100-500mm f/4.5-7.1L IS USM with the teleconverter, it will not allow you to set the lens to anything less than 300mm in focal length due to the design of the teleconverter and rear internals of the lens. Basically, you won't be able to zoom wider than 300mm when using the teleconverter.

Does this Canon Extender RF 1.4x give us a better image than the EF 1.4x? Is this compatible with the 100-400mm 100-400mm f/4.5-5.6L IS II USM Lens or the RF 100-500mm f/4.5-7.1 L IS USM Lens?
Asked by: Brian
The RF extender is made specifically for the RF 100-500mm lens, and the new super-telephoto lenses. When it comes down to image quality, it is suited specifically to get the most out of the RF lenses. It is not compatible with the EF 100-400mm or any EF lens for that matter.
