1.4 iii extender on 5D mkiv and 80D

I was lucky enough to borrow the 1.4iii extender this weekend. Both photos taken with same lens/extender combination 100-400 f4.5-5.6 L is ii.. I like it, seemed to focus quickly and accurately (most of the time). A shot from the 5d mkiv and the 80D, both at 560mm. no editing other than exposure bumped up a little. I wanted to post dng. or raw but apparently that's not an option for me yet. I would definitely recommend this extender for either camera. it definitely makes the 80D really reach out. enjoy and feel free to comment.5D mkiv  100-400 f4.5-5.6 L is ii with 1.4 iii extender

I have the 1.4X III and use it with 80D and 100-400mm II lens. It works well in my opinion. Only slight decrease in AF speed. Otherwise everything looks good to me. The lens and TC combo also works with EOS M5. Though there can be more hunting with the TC when without.

I use the 100~400 II and Extender 1.4× III combination on both the 80D and the 5D Mark IV. Results are excellent, and on both bodies more AF points are enabled at f/8 than with f/8 lens+Extender combinations in general.
