The Insta360 ONE R Twin Edition is one of the key configurations of the modular ONE R action camera system. The Twin Edition includes the Core module, 4K Wide Angle Mod, Dual-Lens 360 Mod, and the necessary Battery Base that holds the modules together. The Core module, which is the brain, and any other module of your choice, mount side by side on the Battery Base. The different modules can be swapped in interchangeably next to the Core module. A 1" Wide Angle Mod, which captures 5.3K resolution video, is also available, sold separately, and can be swapped in. The ONE R allows you to approach different applications with one system.
