Bro. Parfocal means the focus will stay at around the same spot even if u zoom in or out. It does not mean the 5d3 can af with that lens. Its two separate thing. The 5d3 can af with all th canon lenses in video mode.
hmm, maybe I misunderstood the below comment on "video is manual focus only" and I went to try..
Video is manual focus onlyOnce you zoom, need to manual refocus…it's a skill and i believe there are "professionals" hired just to focus when zooming for videos
