Not sure How the "No it does not" comment relates to either my quote of BigAl007"s. We all three agree you can utilize a 1.4x extender with the Canon EF 100-400mm on the 80D and still have AF access to 27 focus points. Maybe I'm missing the point of your post.

No, we do not agree. That is simply not true.

The 80D has 27 f/8 AF points with the 100-400LII & 1.4X III TC.
The 80D has 27 f/8 AF points with the 200-400L and 2x III TC.
With the ORIGINAL 100-400L and 1.4X III, it has one f/8 AF point.
With the ORIGINAL 100-400L and 1.4X II it has one f/8 AF point.
With the 100-400L II and and 1.4X II, it has one f/8 AF point.

There are only TWO lens/TC combinations that yield 27 f/8 AF points:
1.) 100-400L II AND 1.4X III TC.
2.) 200-400L and 2X III TC.

With ANY OTHER lens/TC combination at f/8, the 80D has ONE f/8 AF point.
I hope that clarifies the issue.

We're still on the same page. I didn't mean to imply that all compatible lenses could take advantage of 27 focus points at f/8. That is why I specified the 100-400 L. And although I may have inadvertantly forgot to indicate version II, since it seems like most of the 100-400 users here are using the most current version, that's the lens I was referring to. I should have been more specific.

You have access to the 27 AF points on the 80D provided the 1.4x is the Canon EF III version and the lens is either the Canon 100-400 II or the Canon 200-400.

For any and all other lens and converter combo's it is only the one single centre point @ F8.

In which case the 7D II can provide better AF as it has use of the 4 surrounding points too.

I also understand the 7D II is wired to provide faster initial drive with some if not all of the series II Canon white lenses which will also result in faster AF acquisition.

So whilst the 80D may have a slightly better low ISO dynamic range and 4 more Mp to crop from, as far as the initial question of which has the best AF then the answer has to be the 7DII.

Almost. I see what you meant, but wish to correct and clarify. The 80D can utilize all 45 AF points the 200-400 and 1.4X II or 1.4X III. That combination is only f/5.6. To get 27 f/8 AF points with the 200-400, you will need the 2X III. The 200-400 and 2X II will only have 1 f/8 AF point. Not that it matters to me. I can't afford the 200-400L.

All is good Wilt and Al. I just wanted to be specific. (Primarily because I was upset at only having one f/8 AF point with my 100-400Lc and 1.4x II.) :)

Sorry should have specified 200-400 with internal 1.4x in place AND external 1.4x EF III ( to get to F8 ).

I wonder how many other people have been/will be caught out expecting 27 point AF @ F8 only to have 1?

:oops:

For a harpy as I'm being, I forgot all about the internal 1.4X! Thanks for setting me straight. Now send me $10,000 so I can get the lens. :)

Thanks for sharing your experience. The low-light 80D advantages you mention are compelling, so I have ruled out the 70D and am now pretty much comparing 80D vs. 7D Mk II.

Just remember that the 7D2 and 80D are matched for low light AF acquisition. The 7D2 has slightly better high ISO noise characteristics as well (less troublesome, easier to mitigate in post).

LOL will do, just send me a 600 F4 or a 500 F4 plus a 70-200 F2.8 in return ߙ

The 80D does not have 'spot'. The 80D's 'zone' AF is very much like the AF w/8 surrounding points of the 7DII. The 4 extra points is unique to the 7DII.

But is that Zone on the 80D act like auto where it will pick the point with most contrast? unlike on the 7DII with expansion of 4 or 8 it is using the center point of the group and only goes out to them to keep the subject in focus that was aquired with the center point

7D2 is the superior AF choice. No doubt.

I'm looking at both as well and thought the 80d had better high ISO performance. Just about everything I have read has indicated this.

I don't know what you have been reading but everything I've seen suggests the opposite, 80D is better at low ISO and 7D2 is better at high ISO.
Not that I think there is enough in it to make anyone choose between them.

Personally I vote for the 7D2, it is definitely the better camera, unless you are heavily into video then the 80D could be more suitable.

I spent a fair amount of time reading reviews and downloading files to compare noise levels between the 60D/70D (which I owned and have files from) and the 80D. There is a steady progression of improvement in high-ISO performance through these three bodies, with the 80D being a bigger leap. I can't compare it to the 7D2.

In all of my readings, I found most reviewers give a slight (almost imperceptible) edge to the 80D in JPG. Seems most agree that if you are shooting raw, the 7DII has the advantage (at high ISO). My personal opinion is that if you are shooting either camera JPG at ISO 6400 and higher, you are leaving IQ behind.

A thought or two. There isn't enough difference between the 80D and 7D2 wrt noise to make that a decision criterion. If you need the best AF, get the 7D2. If you need the best video/LV, or have a smaller budget, get the 80D. Noise is not a factor when the choice is 80D or 7D2.

If noise is high on your priority list, APS-c bodies should not be.

EDIT:
Almost forgot. If TeamSpeed tells you the 7D2 is better at high-ISO than the 80D, just take it as gospel. His high-ISO works is amazing. Don't take my word for it. Look for yourself.

Thanks to all who shared knowledge here. I decided on the 7D Mk II and picked up a refurb. My thinking was that AF capability is more important for wildlife and action. It will also make shooting with an ultra-telephoto much more forgiving. I picked up a Sigma 150-600 C for BIF, etc. and I think the 7D2 is the perfect compliment to it, at least for me. I get the crop factor for serious reach, plus the better AF system.
