DJI may be the big dog in drones, but it plays third fiddle to GoPro and Insta360 in the action cam market. To better stand out, the company has launched the Osmo Action 6 with a pair of innovative features. The first is a big, square sensor that boosts video quality in low light, while making it easy to output both horizontal and vertical video. The second is a variable aperture for flexible shooting in both bright and dark conditions.
