Product Highlights
  • EF Mount Teleconverter
  • 1.4x Magnification Factor
  • Microcomputer Controlled
  • Communication Between Lens & Camera
  • Spectra Coating Reduces Ghosting/ Flare
  • Protective Fluorine Coating
  • Dust and Water Resistant
  • Compatible with Select EF Mount Lenses

The Extender EF 1.4X III from Canon is designed for select Canon EF mount L-series telephoto lenses. It increases the focal length of a lens by a factor of 1.4x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it combines redesigned optics, improved data communication between lens and camera and enhanced environmental protection. It is ideal for photojournalists and wildlife, nature and sports photographers who need to get close to distant and challenging subjects and it reduces the need to carry heavy telephoto lenses.

The Extender EF 1.4X III features seven optical elements in three groups and all optical elements have Canon's Super Spectra coating to reduce ghosting and flare. A new Fluorine Coating on the front and rear elements makes marks, such as spots left by water or fingerprints, much easier to clean than standard coatings.

To facilitate the accurate transfer of imaging data between the lens and camera body, the extender features an integrated processor which ensures all focusing, metering and ID information is available - allowing the photographer to capture balanced, well-exposed images. When combined with the latest range of premium Canon L-series lenses, these extenders enable AF accuracy even when capturing moving subjects. When attached, the 1.4x extender reduces the effective maximum aperture by 1 stop.

A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly, reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canon's professional products, and are resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.

Note: This converter is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L. Additionally, please see the lens and/or camera body manual for full autofocus compatibility information with the Extender EF 1.4X III.

    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.

      it's an excellent way to increase the focal length of the selected Canon lenses.
      The image quality is excellent with my 70 to 200 F for lens. I highly recommend in as an alternative to a second lens.

      • Longer Telephoto

      Comments about Canon Extender EF 1.4X III:

      Extenders have always been questionable to me. When you have a high quality, expensive lens, you don't want image quality degraded in order to increase focal length. The only compromise I can see when using the Canon 1.4X III extender is that you lose an F stop. But I don't see any loss of image quality when using the 1.4 with a Canon EF 135 F2 lens.

      It is unfortunate that it is not designed for the Canon EF 70 - 300mm zoom but it can be made to work at the longer focal lengths though I don't really recommend it.

      The extender is a lightweight addition to a camera bag – much lighter than having a longer lens to haul around. So if you need a longer focal length for occasional use and want to save on weight and on cash, this is an excellent solution.

        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.

                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.

                          Comments about Canon Extender EF 1.4X III:

                          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.

                                Works great on my 70-200 lens gives that extra reach when needed. Great image quality. It's not heavy just rember to mount it on the camera first.

                                    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.
