The autofocus is blistering! I honestly can't see any difference between the native RF and the EF with adaptor (I'm sure there's a geek page somewhere, where they show a 0.002% drop in something-or-other, but for my useage it's great).
Have you seen the animal-eye-AF? There's some black magic and witchcraft in there which means it's able to lock on to both animal and human eyes and track them.
The only thing I might be wary of is using an adaptor and the Sigma 'cause that's one beast of a lens! I used to have one and it weighs a ton! I'd be windy about suspending the weight off the front. There are a couple of RF primes in the 600-800mm range which are pretty cheap relatively speaking; the downside is f11, but with in body stabilisation plus lens stabilisation it's apparently not bad.
If you're a birder here's a couple of Caracara on a stick. First time we saw them we were all "ooooohhhh, what are they? *clickclickclickclick*". After a few days we realised they're kind of South American bin chickens and are everywhere.
