In this video I review the Insta360 X4 Air, which is basically the third consumer 8K 360 camera from Insta360—and maybe the lightest 8K 360 camera on the market. I shot real footage on it to show you the quality, and the big headline is the weight: my unit measured about 167.7g, which honestly feels like air compared to the X4 (over 230g). Even with the smaller body, X4 Air brings a new sensor setup (dual 1/1.8" sensors), 8K30 capture, and 29MP photos with PureShot. I also walk through the unboxing (I had the starter bundle), the new 120cm invisible selfie stick design, and the camera’s updated hardware—especially the replaceable lens design with threads and that nano coating on the front glass, very X5-like. On the software side, I show the menus and the features that matter: 8K30 Active HDR (sensor-level HDR), Adaptive Tone (migrated down from X5), and Portrait Mode for nicer skin tones. I finish with a quick charging speed check (15W, and I saw about 8.8W fast charge), plus my feature requests: higher-res photos (ideally 116MP), PureShot for single-lens, and 10-bit color—because I really think Insta360 can unlock more via firmware.
