Excerpt: I use the 1.4x with my Canon EF 100-400mm f/4.5-5.6L IS II USM Lens. This allows me to capture birds in flight at 560mm on my full frame Canon 6d. You sacrifice an f-stop in light. So far with this combination I cannot autofocus I've only been able to achieve only manual focus.
Excerpt: Upgraded from the 1.4X II to use with Canon 300mm 2.8 IS II and 1D X. Was hoping to see better IQ from II to III, but on still subjects, not seeing it. Hopefully, AF will be a little faster on moving objects which I haven't had the opportunity to try yet.
Excerpt: -I use this extender when taking photos of skiers
-It does not degrade photo quality, and does the job of extending beautifully.
-Unfortunately focusing with this extender is more difficult. Occasionally photos will be soft or completely out of focus.

Summary: I was never happy with the speed of focus or image quality with this extender. I had tried the 1.3 and loved it and being greedy, thought "heck, might as well go big and get the 2.0". That was my mistake I guess. I sold it later and haven't replaced it to date.
Excerpt: I use the Extender EF 1.4X III by Canon for nature photography. I use it with a Canon EF 70-200 L IS II USM. I get clear crisp pictures with this extender. Can't wait to see what it does on a bigger lens.
Excerpt: Having a buch of fixed focal length lenses in your bag is great, but very expensive! This extender does that job for a whole lot less and is as sharp as without it! Good investment for any professional!
Excerpt: So far I've only had a couple opportunities to use this. I have a photo of a Bald Eagle that would not have been possible without it. Many professionals say extenders decrease photo quality. That may be true with some extenders but the picture quality with this one seems to be unaffected.
