Insta360 has introduced the X4 Air, a compact and lightweight addition to its 360-degree action camera lineup, arriving shortly after the release of the X5. Positioned below the flagship model, it retains 8K 360-degree video recording while reducing size, weight, and cost.

The X4 Air records 8K 360° video at up to 30 fps and 1080p slow motion at 120 fps when using a single lens. However, its 4K video is limited to 50 fps, whereas the X4 and X5 can reach up to 100 fps. Still image capabilities are reduced to 29 MP, far below the 72 MP resolution of the higher-end models. Despite these limitations, the camera employs larger 1/1.8-inch sensors than the X4, a change that according to the company improves detail and color reproduction. The sensors remain smaller than the 1/1.28-inch units inside the X5, affecting low-light performance.

The Chinese company has focused on weight and portability: the X4 Air weighs 165 g and measures 113 mm in length, making it around 38 g lighter and shorter than the X5. The battery capacity is also reduced, delivering up to 88 minutes of 8K 30 fps recording instead of 93 minutes. The camera, however, uses a removable lens guard and supports replaceable lenses, extending durability and offering a key advantage for field use. It is waterproof down to 15 m (49 ft) without external housing and includes voice and gesture controls, horizon leveling, and stabilization technology.
