A clear improvement over the previous version

  • Excerpt: I purchased this teleconverter to replace the 1.4x Mark II version that I had in my kit for the 6-7 years or so. My use for this converter is not typical at all. As an archtiectural photographer, I make extensive use of the new line of Canon TS-E lenses and I wanted to see how well this...

  • Summary: I own the Canon EF 500mm f/4L IS Lens. Not the version II. The original lens. I also own the 1.4x teleconverter version 1 also. I bought this for bird photography because the 1.4x was not quite close enough to suit me on the smaller birds.

A Precision Piece!

  • Excerpt: I was skeptical about using an extender but this makes a great deal of difference on my 70-200 f/2.8 II. I was considering a 300mm lens, but really like the fixed aperature and that everything is "internal" to the lens (barrel does not extend or rotate) like my old 70-300 f/4.5-5.6 non-L.

Excellent addition

  • Excerpt: I shoot a 5D MkIII and information on the extender was not consistent. Some reviews indicated that the extender would not autofocus when used a 100-400L IS lens. I learned in a B&H review that the lens would autofocus if the camera's firmware was updated. This proved to be correct.

1.4x III

  • Excerpt: A well built piece of equipment, bought it to use with the 100-400mm II and a 7D2. The pictures are sharp and the AF to a certain extent seems to work flawlessly. Definitely a keeper.
  • Pros: Easily Interchangeable, Fast / accurate auto-focus, Strong Construction
  • Cons: None to date

Wonderful -- great for birding!

  • Summary: WOW! I looked at the photos with and w/o the extender, and couldn't see any difference! So there is no reduction of image quality, which is awesome. Of course, with the 7D ii, adding it means reducing the focus to only center and surrounding four AF points, but I don't see a reduction of AF speed...

A must have for every photographer.

  • Summary: I use this with my Canon 500mm lens and the images are flawless. Auto-focus speed is a bit slower with this extender but if that's not a problem for you, then this is a great way to get a little extra reach with your telephoto lens without degrading the sharpness of the photograph.
