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.

      I wanted to get a little more 'reach' from my lens for wildlife photos. The 1.4X III does this without any loss of quality to the image.

          I bought this to go along with my new Canon 100-400 f/4.4-5.6L is11 Lens, Althought it doesn't work in auto focus, It works great in manual focus which I use a lot when I'm on my tripod anyway.

                  Definite improvement over 1.4x II version. When used with the second generation super telephoto's minimal drop off in IQ, barely notice increase in focus speed.

                  Great for ducks and shorebirds that are not moving quickly.
                  Need to upgrade your Canon Firmware on camera in order to use automatic focus with extender at f8 and slower. Haven't tried this yet.

                    It really works well with my Canon 100-400 mm l lens. The carrying pouch makes it easier to keep it clean. For the investment, it makes up for the price of a very expensive lens longer than the 400 mm end of the lens.

                    I use the 1.4X Extender with my 400 mm Lens for shooting wildlife; mostly Bald eaagles in flight.. The extender does not distort my photos andd works well in AF with my 5D Mark III... I have nothing negative to say about this extender, except you cannot set an f stop below f8.. A great addition to my camera bag.

                    I use this 1.4 X TC III to gain extra reach with my Canon 100-400 f/4.5-5.6L IS II lens. It turns the lens into a 140-560 mm f/6.3 (approx) - f/8 lens. I lose a little sharpness and contrast with the TC but it's still pretty decent. The autofocus also slows a little but not much. It also adds a bit of weight. It probably is the best TC available for this lens. and also the most expensive! Note that unless your camera can autofocus with a lens as slow as f/8, you won't be able to use autofocus. But it's way cheaper than buying a Canon 600 mm lens, and the image quality with the Canon 100-400 seems to be about as good at 560 mm as the Sigma or Tamron zooms are at that focal length.

                    I use the extender on a Canon 100-400 lens. My only comments are why did I wait so long to purchase this; and why did I stick with my other extender for so long when the quality just wasn't consistent. The only problem I have is that because of the extra 8 ounces, I can no longer hand hold even in bright light.

                      I bought this to pair with the Canon 400mm f/5.6 L lens and it is terrific and that gets me out to 896mm with my APS-C (1.6x Crop Factor)sensor.
                      The extender still makes for a comfortable hand carry package

                        Comments about Canon Extender EF 1.4X III:

                        I was quite disappointed that I could not use one of these with my Canon 70D with my Canon 100-400mm L lens, however all of that changed with my recent purchase of a Canon 7D Mark II which in fact will allow AF with that lens. I have been getting tack sharp results at 400mm with the Canon lens and although I have seen reports of diminished sharpness with extenders, that is simply not the case with this extender. I was very pleased after my first day in the field to discover that shots taken at 560mm were tack sharp and I was able to quickly lock on to moving targets such as birds in flight. I this extender as a must have in everyone's bag! In addition, I hand carry my rig with just a wrist strap (Black Rapid) for security and the addition of the extender still makes for a comfortable hand carry package that gets me out to 560 mm with my APS-C sensor.

                        Comments about Canon Extender EF 1.4X III:

                        I purchased the Extender EF 1.4X III to replaced version II. The sharpness is overall improved with excellent contrast and color. The only draw back is the steep price. I own two of these now so I don't have to keep swapping between the 70-200mm IS f/2.8L II and the 300mm f/2.8L II when I'm on assignment. I would have giving this product 5 stars if it is $ cheaper.

                        I bought this to pair with the 300mm f/4 L and it is terrific.

                          i have a 2X extender and found a good reason to have a 1.4 extender. I use these extenders for wildlife photos.
