Insta360 ONE RS Twin Edition Interchangeable Lens Action Camera

Insta360 ONE RS Twin Edition – A Two-in-One Action and 360 Camera Built for Underwater Storytelling

The Insta360 ONE RS Twin Edition is a modular action camera system that gives you two completely different lenses in one package: a 4K Boost Lens for sharp wide-angle footage and a 5.7K 360 Lens for fully immersive, all-direction capture.

If you are a recreational diver or an active underwater shooter who wants creative flexibility without carrying two separate cameras, this setup is worth a serious look.

What You Are Actually Getting

The Twin Edition ships as a complete system, not just a camera body. In the box you get:

• 4K Boost Lens for standard wide-angle video and stills
• 360 Lens for spherical, all-around capture at up to 5.7K
• ONE RS Core, the brain of the system that both lenses attach to
• ONE RS Battery Base
• Lens Cap for the 360 Lens
• ONE RS Mounting Bracket

The Core is the shared processor. You swap lenses depending on what you are shooting that dive. That modularity is the defining feature of this camera, and it is what separates it from a standard action camera.

Waterproofing: What the Rating Actually Means for Diving

The ONE RS Twin Edition is waterproof, but the depth rating is not confirmed. Before you take this underwater, confirm the exact rated depth with Insta360 directly or through product documentation. This matters enormously for diving, where pressure increases by one atmosphere every 10 metres.

Do not assume any action camera rated "waterproof" is safe at recreational diving depths without a confirmed depth limit. Many action cameras in this category are rated for surface water sports or shallow snorkeling, not scuba depths. A housing may be required for deeper dives.

The Two Lenses and What Each One Does Underwater

This is where the Twin Edition earns its place in a dive bag.

The 4K Boost Lens shoots up to 4K at 60fps and can reach 6K in widescreen mode (6016x2560). For underwater video, the wide angle captures reef walls, wide-angle fish schools, and diver silhouettes with strong detail. At 1080p it goes up to 200fps, which gives you real slow-motion capability for fast subjects like reef fish or bubble streams.

The 360 Lens records in all directions simultaneously at up to 5760x2880 at 30fps. Underwater, this means you never miss a shark passing behind you or a turtle coming up from below. You can reframe the shot after the dive, choosing your angle in editing rather than committing to one direction while you are actually in the water. That is a genuine advantage when you are also managing buoyancy, air, and navigation.

Stabilization

Both lenses use FlowState stabilization, processed in-camera through the RS Core. For underwater footage, this matters because even small movements from fin kicks, surge, or breathing create shake that makes footage hard to watch. FlowState handles this without requiring post-processing, so your clips come out usable straight from the camera.

Stabilization is listed as hybrid, meaning it combines optical and electronic methods.

Photo Capability

With the 4K Boost Lens, the camera shoots 48MP stills. The sensor is a 1/2-inch CMOS, which is a standard action camera size. It is not a large sensor, so in low-light conditions typical of deeper dives or murky water, you will see the same noise limitations you would expect from any compact action camera. The aperture is f/2.4 on both lenses.

Shooting modes include Standard, HDR, Interval, Night Shot, Starlapse, Burst, and PureShot. Active HDR is available for video and is useful in high-contrast scenes, such as shooting upward toward the surface while a subject is in shadow below.

Practical Specs Worth Knowing

The V90 memory card requirement is worth noting. V90 is a fast card class, and not every Micro SD card you own will meet it. Using a slower card with 6K or 360 footage can cause dropped frames or recording failures. Make sure your card matches before your dive trip.

Editing and the AI Tools

The Insta360 app connects over Wi-Fi or Bluetooth and includes AI editing tools that can automatically cut and assemble footage. For 360 video especially, the reframing and horizon-lock tools are where a lot of the creative work happens after the dive. This is not a camera that demands heavy manual editing, which suits divers who want shareable footage without spending hours in front of a computer.

Who This Camera Suits and Who It Does Not

The Twin Edition is a strong fit if you want creative flexibility on a single dive, shoot a mix of standard and immersive footage, or often find yourself wishing you had captured what was happening behind you.

It is not the right choice if you need confirmed deep-water depth ratings, shoot in very low light at depth regularly, or want raw file formats for professional color grading. The JPEG-only stills and 1/2-inch sensor are real limits in those situations.

It is also worth being clear: the modular design means you carry two lenses and swap between dives, not during them. If you want to change shooting modes mid-dive, this system does not support that.
