  • Excerpt: According to what I read, this was compatible, or "would work with" the 100-400 IS ....The lder versions would not. But as it turns out the newer improved lens would also "not work"....except on manual focus..... waste of my time and money and belief system ....

  • Excerpt: I bought the 1.4x III purely for the supposedly improved AF focusing functionality. I'm a birding & wildlife photographer in South Africa, & thought this would bring a new dimension with the increased zoom and AF function. After much research I believed the AF function would work.
  • Cons: Blurry Focus
