The Osmo Action 4 isn't revolutionary in any respect except one – a significant one: the image sensor size leapfrogs the market leader. The camera also extends horizon balancing to useful resolutions and frame rates, and the waterproofing can go deeper. It adds up to mean, except a few scenarios, if you're happy with 4K, this is the best action camera of all.
