AF settings used for all the recordings: AF Area Full with Face / Eye detection.
Another note - the AF on the Sigma 24-70 DG HSM OS Art mounted via MC-21 adapter was way too loud for practical use. And the wobbling in the beginning of the shot with this lens is not me kicking the tripod, it seems like the IBIS and optical stabilizer in the lens had to figure their stuff out. So I'm guessing there may be some firmware update coming to fix that issue with the MC-21 adapter. But this and the noise aside - it actually performed better than I expected.
