Looking for an bridging body: 80D?

[xps]

My 7D Mk II is suffering from persisting problems, so I´d like to buy an bridging body, until 5d MK IV arrives.

How does the 80D´s AF work compared with the 7D Mk II?
Is the AF much slower? How big is the advantage of the 80D´s 27 point AF at F8? How fast is it, if you go to f8 with an lens/converter-combo?

I read that the image quality is better than the IQ of the 7D Mk II. What is the highest ISO, you can shoot at, without visible image quality impairment?

Hi xps!

I have neither the 80D nor the 7D2. So sorry if you want to see personal experience only.

But if you read the reviews of Dustin and Bryan and know their reputation I'd go for the 80D.
Both say that the AF is great, a big improvement over the (old) 70D/7D AF and coming close to 7D2.

Dustin says:
The upgraded AF system makes it a viable competitor to the 7DII, though that camera should probably still be the ultimate choice for sports or wildlife shooters. But the Canon EOS 80D is the jack of all trades, good enough at everything to make many owners very happy.

I hope, I could help a little bit.
