Hi!

I am considering the Sigma sports version vs the RF 70-200mm or even the EF version 3.
My concern with the RF version aside from the much higher price is the heavy focus breathing where 200mm is much shorter than the old EF but of course it does focus closer.

I would like great Eye AF accuracy and overall fast AF so perhaps that means the RF but maybe the Sigma is not far behind? I love my other Sigma glass adapted so far.
This will be on the R5 and R6
Thanks

I ordered the Sigma 70-200mm f/2.8 Sports. I will receive it monday, or, if I'm lucky, this weekend.

If it's here Saturday I might find some time to test. What do you need to know? Walking speeds, running speeds, biking speeds? Environmental body, body filling the frame, from the waist filling the frame up or head and shoulders filling the frame? @200mm or other focal lengths?

That is awesome. Walking speed will be good just for runway stuff. 
Most of the time I will use it in the studio and I like 2.8 many times for some blur of textured backdrops so 70mm 135mm and 200mm tests of Eye AF will be awesome.
If it's like my 105mm 1.4, it never misses even at 1.4 and up close although most of the time I am shooting mid to full body.
Thanks!!!
