Thanks, Ka Bobby. That was filmed with a Sony RX10 M4, which performs better than DSLRs at macro and BIF videos. For BIF stills, I continue to prefer DSLRs primarily because of the brighter viewfinder with instantaneous feedback. The EVF of mirrorless cameras has a slight delay, and this makes BIF shooting tougher. Also, EVF presents the image with the aperture stopped down (when not shooting wide open), resulting into a darker view. An optical VF always presents the image at wide open aperture, stopping down only at the moment of capture.
