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.

Solidly built Product

Comments about Canon Extender EF 1.4X III:

I liked the Canon EF 1.4X III, but I returned it 'cuz it didn't work with the Canon EF Lens 100-400mm's AF settings while the Kenko's WORKED. Besides, the price is quite stiff for something that doesn't work with the same brand of lens. Sorry, Canon, you have to make your extenders work with ALL of your lenses with AF settings for the PRICE.

Comments about Canon Extender EF 1.4X III:

Purchased the Canon Extender EF 1.4X III to use with my Canon EF 70-200mm f/4 IS USM lens and Canon 80D camera. Since the 80D has a APS-C sensor this gives me up to 320mm when using the 70-200mm lens. I have used this combination when shooting some wildlife as well as a Blue Angel airshow with great results. Photos are sharp! The extender is small so I easily carry it around in my camera bag in case I need a little extra range. Very pleased with my purchase and have no problem recommending, but be sure to check compatibility first with your lenses and camera.

    Comments about Canon Extender EF 1.4X III:

    I do a lot of bird photography with my Canon 7D Mark ll and Canon EF 100-400mm lS ll USM. This extender allows me to use auto focus. It is fast and almost to the shot crystal clear. Once I put it on the camera I haven't been able to remove it, I love it! It allows me to get many shot that otherwise I would have attempted to violate the birds space and loose the shot. Today, I photographed a hawk about 100 feet in the air leaving a tree top and it locked on to it and remained in focus until I let up on the shutter button. Absolutely amazing! I can't say enough good things about this purchase. I was very skeptical because I had an old Canon 1.4 and 2.0 which I had to use manual focus. I was never able to get my photos to be as clear as without the extender. I can't tell the difference in clarity with or without the extender now. What a beautiful piece of glass!

      I use this with my Canon EF 100-400mm IS II lens on a Canon 7D Mark II. Works as I expected and supports all lens features. Limits the range of autofocus points, but this was expected.

        I had the Extender EF 1.4X II by Canon. It would not allow autofocus when used with my EF 500mm 1:4 L IS USM lens. The new EF 1.4 III allows autofocus. I'm very please with the results. Focuses quickly and images are clear and sharp.

        With 80D and 100-400 zoom

        By Doug99

        from Michigan

        Comments about Canon Extender EF 1.4X III:

        With the Canon 80D's AF capability now out to f/8, I can now get a little more reach out of my 100-400mm (ver.1). You lose a stop of light, but images looked great on the overcast day that I tried. Can only expect superb results on bright sunny days.

        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 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.

                            Used with a 70-200 2.8 II for that exrtra reach and only one stop loss with the 2.8.
                            Amazing images on the 5ds-r

                            Must have in your bag!!

                              Great with almost Zoom lens for extra reach. Fast Focus, but do lose a bit a focusing speed with extender.
