Boosts in all the right places make the Hero9 Black the pinnacle of action cam excellence, but if you don’t need 5K, you may well be better off with last year’s model.
Better battery despite two screens; Sharp and stable 5K video; In-device horizon levelling
Overheats after 30 minutes of 5K capture; Slightly narrower field of view than Hero8 Black; Bulkier than the dinky Hero8 Black
