While GoPro has been a leader in the action camera game for many years, DJI is putting up a fearsome fight to claim dominance with the Osmo Action 4. It boasts many of the top-tier features of the previous Action 3, including excellent stabilization, solid waterproofing, front and back touchscreens, and great battery life. However, DJI also imbued this model with a larger camera sensor and higher color depth, making the Action 4 a strong contender for the lead.
