> Not sure the metric, but SLRs still own the focusing crown for most action-based photography (though the mirrorless cameras are getting closer to being good at it) I'm not sure this has been true since the Sony α9. Its autofocusing abilities are amazing , and that's coming from me - a Nikon fan and D500 owner. If I shot people rather than wildlife, I'd probably switch for the eye-AF alone.
The Nikon D5 still has the crown when you add in that test and percentage wise will beat Canon/Sony. In absolute numbers, because the Sony shoots so fast it can bring home more 'keepers' in terms of numbers of photos though.
And the focus point coverage is WAY bigger on the a9, so overall I would call it a tie depending on what you are shooting.
