The Insta360 ONE RS 4K Edition is a modular action camera system with interchangeable lenses. This edition is designed for action sports and includes the ONE RS Core module, the ONE RS Boost 4K lens, the ONE RS battery base, and a ONE RS mounting bracket. The 4K Boost Lens captures 4K60 video, up to 6K widescreen video, and 48MP still photos, and it features a 1/2\" image sensor with Active HDR support. The ONE RS features 21% more battery capacity than the ONE R, and it also features crisper audio with three microphones and faster Wi-Fi transfers.\r\nWhen the 4K Boost Lens is set up with the core module, the core module\'s touchscreen live-view display can be used as front- or rear-facing, allowing you to shoot standard 4K video as well as selfie and vlog videos. The 4K Boost lens also supports improved, built-in FlowState stabilization that uses a scene-detection algorithm to stabilize your shots, so they come out more balanced and professional-looking. Like all the other modules, the 4K lens is waterproof down to 16\' when assembled with the core module, battery base, and mounting frame, with no waterproof housing required.\r\nNote: The different modules are waterproof only after being fully assembled on the Battery Base and installed in the included Mounting Frame.
