Work very well with my 70-200 f4 L and my 7D with a magnification of 1.6 to 280 mm
I lose nothing in image quality as it can be perceptible. At 5.6 and a focal that it is even sharper. Uses for birds and photography fox and I am extremely satisfied.
But only compatible with the Series L, not all lens.
Also very useful when traveling.
Even though it is a bit expensive but it is very good quality. You pay for what you have!
A must to have!!
4 Start because it's not compatible with all lenses
You won't regret.

Look the picture at 280 mm, F8, 1/500 iso 200
No modification could be at 5.6 too,and it's not my best one!

I have Canon 70D and a EF 100-400mm 1:4.5-5.6 L lense. The optics was good when taking some pictures of birds and a sunrise from a distance. However, the AF did not work. I read all the literature and based on that I thought the AF would work. I called Canon and they stated it would work only on certain cameras of their line, but not the 70D. I was disappointed because I paid the extra money for AF. I returned the extender and purchased a cheaper one and will probably have to manual focus. So I would check with Canon before purchasing this extender if you want the AF to work.

Limits with small frame camera body

By Ops

from Ma

Comments about Canon Extender EF 1.4X III:

I bought my canon EOS 80D and the Canon EF 1.4 X despite the warnings that the auto focus may not work with lenses 5.6mm. I planned to use the extender with the CANON EF 3.5-5.6 L 100-400 Zoom lense for bird photography with all automatic settings. The first test was disappointing at the full end 400mm and even slightly less. The auto focus did not seem to work. I was also on a learning curve with the upgrade of the camera body from the EOS 20D to the EOS 80D. My second attempt of mating rituals of Wood ducks was a spectacular improvement. I decided to set the lense back to 300mm and the auto function worked. Then I inched up to 350mm and then almost to 400. It's not perfect with the small frame camera body, but it's a major improvement than without the extender. A faster lense would be best bet. But, this will garner some great photos until I can get a faster lense. The extender is easy and quick to attach to the lense and camera body and to detach. I had reservations buying this with my camera set up and photo needs but I'm ultimately glad I got it!

      I bought this to use with an EF 100-400 ver2 lens. It works with the lens very well. Auto focus feels just as fast as with the bare lens.

        This single piece of equipment has changed the way our journalism team is able to shoot action sports photos. It's compact size makes traveling with an additional lens easy, and it's very easy to put on the camera when needed. Great addition to our photo equipment.

            Got this to use with my new 100-400L MKII lens, works great, with some really nice sharp pictures. Not for fast moving objects, but works great for slower targets or a non-moving object. I'm very happy with this unit.

                I use this on my Canon 70-200L and 100-400L lenses to get that extra reach and find the trade-off for one stop of light to be well worth the results. I see no appreciable delay on autofocus speed or in image quality. No doubt there are other opinions on these things here, but for us mere mortals this extender does exactly what it is supposed to.

                I find this all-Canon combination to give me nice flexibility and is a great value compared to spending way more for a 150-600mm third party lens to get that extra reach.

                The build quality is typical of Canon L lenses -- top notch.

                          Can your telephoto lens ever reach as far as you'd like it? Yeah, sometimes. But for the rest of the time, this handy little add-on pushes that reach out farther, without sacrificing quality or speed of AF.

                          Comments about Canon Extender EF 1.4X III:

                          Adding a 1.4 extender to my 100-400 lens gives me a lightweight, although slightly slow, alternative for wildlife and sports photography to a 150-600 lens.

                          Remember that it will not autofocus unless the firmware is upgraded.

                            Purchased and returned a Kenko 1.4 teleconverter when I discovered it did not work with the new 7DM2 and 100-400 L M2.
                            The Canon 1.4 teleconverter does everything I expected and more. Fast autofocus and excellent image quality for birds and other wildlife.

                            I use the 1.4x with my Canon EF 100-400mm f/4.5-5.6L IS II USM Lens. This allows me to capture birds in flight at 560mm on my full frame Canon 6d. You sacrifice an f-stop in light. So far with this combination I cannot autofocus I've only been able to achieve only manual focus. With the 1.4x the sharpness degradation of the photos is minimal if at all. I do have the 2x extender which you do have a noticeable drop in picture quality you need a tripod vs handheld to eliminate shake & blur. You also sacrifice 2 stops with the 2x. I prefer the 1.4x combination to the 2x extender I mostly take wild life shots that are hand held. The 1.4x doesn't add much weight or bulk to your set up.

                            I am using this extender with my Canon 100-400 II Zoom lens. Along with my small sensor Canon 7D Mark II it gets me to just under 900mm. I lose one stop of light, but IS is amazing and I have taken hand held tack sharp images at 1/160th of a second! I am a bird photographer and can't recommend this extender enough. I lost sharpness with the old extender and old 100-400 mm lens. Not this combination. Miss being able to use all my focus points, but it rocks!
