Review: Decent extender for RF Lenses - I've used this extender on my R5 with both my 100-500mm and 800mm lenses and it works extremely well. It does add one F-stop but that has been a small price to pay for the extra reach as I photograph wildlife and getting close can be tricky. I have noticed that the auto focusing (particularly eye detection) can be fractionally slower when I use the extender than just using the native lens, but it hasn't been significant enough for me to abandon the idea of using it for the extra reach. Thankfully, the R5 can handle high ISO rates well enough that the loss of the F-stop hasn't stopped me from getting decent photos. In fact, the photos are limited only by my own lack of expertise. It is a very useful addition for squeezing a little extra reach out of my lenses for capturing wildlife in the field. I included two photos I took using the R5 + extender with my 100-500mm telephoto, giving me 700mm for these shots. While I'm not a great photographer, they do give you a feel for what is possible. One note: to install the extender, your compatible lens needs to be fully extended. For example, when I used the 1.4X extender with my 100-500mm Canon RF lens, the lens was fully extended to 500mm before I installed the extender. Until the lens is fully extended, you cannot install the extender. Now, I can inch the lens down to about 450mm but with the extender installed, you're basically "committed" to using the lens at the full reach, which in my case was the full 500mm, giving me 700mm with the two components. If that makes sense.

RF1.4X(N) (4113C002) - Image 1](https://m.media-amazon.com/images/I/61H2+PKd1RL.jpg) ## Questions & Answers **Q: Will x1.4 extender minimize megapixels on canon r6 camera with rf 100-400 is usm lens?** A: No. It will only extend the range of the lens by 1.4 times. **Q: What kind of adapter is recommended for this??** A: There is no adapter needed. You must have a Canon EOS R, R5, or R6 camera to use it AND an RF lens. That is what the RF in the product description is all about. My experience with the EOS R5 and the RF 100-500 lens is that the 1.4 works beautifully. **Q: Does anyone know how this will work on a sigma 18-300mm lens? i have a canon eos 90d.** A: No, this extender will not work with the 90D because it is for the EOS R bodies, like the R, RP, R10, R7, R6, R5 and R3. It is also only compatible with these select Canon RF lenses - RF600mm F11 IS STM, RF800mm F11 IS STM, RF100-500mm F4.5-7.1 L IS USM. In addition, The Sigma 18-300mm lens will not accept an extender on the rear mount because the rear element is not recessed. **Q: I own the rf 2x. it's pretty good. any opinions on whether the 1.4 has image quality superiority enough for an amateur to justify the extra $500?** A: The only difference between the two I can think about is that the 1.5x allows for a little more light to pass though. While I have the 1.5x extender, I still haven't use it since I purchased it. You will have to consider the number of times you may attach the 1.5x to the lens instead of the 2x extender. Now, if the RF 100-500mm lens that I use would have a fixed aperture of f/4, then both the 1.5x and 2x extenders would be perfect. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent extender for RF Lenses *by A***T on February 6, 2021* I've used this extender on my R5 with both my 100-500mm and 800mm lenses and it works extremely well.

I paired it to a Canon RF 100-500mm lens, and everything workers well with, so I can't complain about its performance, including IQ, focusing, and the rest. Be aware that if any of two extenders (1.4x, and 2x) are used with the RF 100-500mm or any other zoom lens like this, the lens can only be zoomed from 300mm to 500mm. Then if you want to zoom back retract the lens to 100mm, for example, that is not possible since the lens cannot be retracted past 300mm (can be extended/retracted only between 300 and 500mm). This 1.4x (or 2x) extender should be just about perfect for using with prime lenses, not zooms such as the RF 100-500mm unless you are photographing under bright daylight. With this lens at 500mm its aperture is around f/7.1 without the extender. The You should lose around 1 "f" stop by adding the 1.4x extender alone. But it should be about perfect with a RF prime. ## Frequently Bought Together - Canon EXT.
