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 wanted to extend the range of my Canon 100-400mm lens. The extender did that well. However, on this lens the extender disables the autofocus making it very difficult to focus on moving objects. Even when photographing still objects, it is difficult. In addition, the extender reduces the clarity of the photographs. I could get a few decent pictures, but tack sharp never happened. If someone has a smaller lens, this might be a great product, but for me it just didn't work out. I returned the item.

    Comments about Canon Extender EF 1.4X III:

    I used the extender to shoot softball with my 70-200mm f/2.8 IS II zoom on my 5D3. The extender worked flawlessly: the 5D3 focused just as accurately as without the extender & exposure was set accurately. It fit the lens & camera perfectly just as you'd expect for a Canon product. The effective 280mm maximum focal length worked fine for shooting action in the infield, but wasn't long enough for the outfield. There was no degradation in focus accuracy or speed that I could determine. All in all the extender met all my expectations & I'm happy I bought it.

      Comments about Canon Extender EF 1.4X III:

      It simply snaps on between your lens and your camera.
      I use this 1.4 on a 5D + 70-200 setup. I shoot from about 8 to 35 yards from my subjects. The 35 yard shot was not selling too well because it was just out of range of interest. By range if interest I mean the subjects could just barely tell it was themselves. So I needed to reel them in another 15 feet or so. This extender did just that and at no visible loss of quality to the naked eye which means none on the printed photo. Keep in mind the 1.4 will raise your F-stop depending on your setup. With my 4.0 70-200 it increases to 5.6. Not much of an issue if your shooting outside. You could also get by with it inside as long as your camera is capable of high ISO without lots of grain (noise). I am still referring to my own setup.
      Bottom line, if you need to reel something in that's just barely out of range, this is the piece for the job. Thanks and enjoy shooting.

        I use this with my 70-200 2.8 IS ii and 7D. I have been very pleased with this combination. It helps me out with some extra reach for photographing waterfowl and small-medium size approachable birds. Autofocus is quick and the resulting images are very sharp.

          I haven't had much opportunity to use the item yet, but fully expect it to work with a 100-400 Canon zoom lens I will be receiving in a couple days. I've always had good service ordering from B&H.

            Comments about Canon Extender EF 1.4X III:

            The extender turns my 70-40,f.4 L lens into a 280 and with my Canon 50D. It worked great for a couple of my granddaughter's softball games -- sharp focus, action frozen, shutter speeds up to 800 to 1000 in both bright mid-day light and even into the early evening. Since my shooting will be mostly these events and being close to the action on the field, the extender is all I need.I have yet to try it with some landscape and wildlife shooting, but if it is done in brighter light I anticipate the same results.I will also give it a try at a minor league baseball game or two later this summer where I will be further away from the action.

                  The 1.4 extender is a nice 'boost' to my 70 - 200 mm lens. Very easy to install, though I generally leave it connected to one lens. It's added focal length with amazing clarity. Not like the dark extenders of the old days.

                    My 200mm becomes a 280mm with the extender, and that is often the exact need in capture for me. Frankly, I cannot tell the difference between the 200mm alone and using it with the extender onscreen, or in print, unless I do the most extreme pixel peeping, which means nothing to the final product.

                    It just works great.

                      I purchased a Canon 1.4X extender for use with my 70-200mm 2.8 IS lens.
                      I enjoy wildlife photography and the extender boosts my telephoto lens without sacrificing a lot of light (one f stop). This extender really allows me
                      to extend my reach to almost 300mm without having to spend the big bucks
                      for a longer lens. This product is well worth the money.

                          Excellent for extending the focal length, but its autofocus doesn't work with the cheaper Canon models (6D and lower). There might be some other limitations.

                                I use this primarily for sports. I have the 70-200mm 2.8 canon lens. I purchased this to extend my zoom as a 300 or 400 super telephoto is not in the budget right now. I love it. Yes, it reduces the f-stop to f-4, but with enough sun, still a great image. Focus seems pretty quick and accurate. I love it.

                                This extender is great it does not slow the lens down and the auto focus works great with it on and no image quality is lost.

                                    I needed a little more reach on my 70-200 F2,8 II lens, and this fit the bill.

                                    I do a lot of roller derby photography - fast moving skaters in a low light environment. My focus seems to be just as quick with the 1.4 extender, and the sharpness is great.

                                    Very satisfied with this purchase.

                                        A good alternative to buying a larger lens. I was skeptical of the loss of quality which I had read about before but that was unfounded. The Canon quality really shows up. I had another converter and was really disappointed. Not so with the Canon when mounted on my Canon 70-200MM.

                                          Gives the extra reach with nice image quality. I really have not noticed any loss of IQ with this extender. Autofocuses nicely. If you don't want to spend the money on a 300mm lens this is the way to go. No regrets in purchasing this.

                                            Well, only inexpensive if you are avoiding the purchase of a longer lens.....

                                            I use it with a Canon 100-400mm zoom. Many reviewers have criticized that setup, but I find it acceptable with a few caveats.

                                            First, on a solid mount and carefully focused, my results have been pretty good. But, autofocus absolutely does not work with my Canon 60D. I just go manual focus and it works fine.

                                            The combination is essentially a 600mm focal length f8 lens with no autofocus. After checking the price of a 600mm f4 autofocus lens, the extender looks a little better. I'll spring for the big lens someday, but not today.
