Insta360 ONE RS Review: A Modular Two-in-One Action Camera

Introduction

The Insta360 ONE RS arrives as a modular action camera that can be configured in more than one way, and the twin edition is the clearest expression of that idea. It ships as two cameras in one: a 4K lens module and a 360 lens module, both sharing the same core body, screen, and battery base.

The design carries over the modular concept of the earlier ONE R, and the parts are interchangeable between the two generations. That means owners of the previous model can add a single new component rather than replacing everything at once.

Who This Camera Is For

This is a camera for people who want one small device to cover several kinds of shooting. Riders who normally carry an action camera for ride footage get the familiar wide 4K view, and the same body can become a 360 camera when the other lens is clipped on.

Because the modules separate, the camera can be packed flat, rebuilt for a different shot, and mounted on existing action camera mounts. The build quality feels premium and the clips that hold the modules together feel solid and confidence inspiring, which matters for gear that is likely to take a few knocks.

It is also a reasonable fit for anyone who already owns ONE R hardware. The new 4K lens can be used on the older camera, so the upgrade path can be gradual, one part at a time.

Main Strengths

Modular Two-in-One Design

The camera breaks down into a battery base, a core unit with the screen, and the lens module. The red battery base detaches cleanly, and the parts clip together neatly before sliding into an open frame cage. Once it is in the cage, the camera is waterproof to around 16 feet, which covers rain, splashes, and an accidental drop into water.

The 4K lens is the more familiar action camera style, a 16 millimeter equivalent that shoots in 4K out of the box. It uses a half inch sensor, which is larger than the sensors in most other action cameras and should help in lower light. Outdoors in bright sun most action cameras look good, but the ONE RS also holds up indoors and in a studio with no natural light.

Stabilization and Low-Light Image Quality

In-camera stabilization, which Insta360 calls FlowState, is the standout feature here. The camera stabilizes footage in real time as it records, so what you see on the screen while riding is already smooth and no post-production work is needed to make it usable.

Footage shot on a cyclocross bike with no suspension, down a short stretch of single track, came out very smooth without any editing or stabilization applied afterwards. That level of steadiness from a small camera is genuinely impressive and difficult to replicate without this kind of processing.

The core processor has been updated since the previous edition, so the camera is faster overall. The touchscreen responds well, Wi-Fi transfer is quicker, and stabilization has improved alongside those changes.

Audio Improvements

Audio has been a weak point for action cameras used on a bike, because wind noise and speed combine badly. The ONE RS addresses this with redesigned microphones, including an additional microphone to improve overall audio quality, and a small foam windshield built into the microphone opening that is hidden inside the housing.

That built-in windshield solves a problem riders often fix by sticking fluffy covers over the microphones, which can fall off. The result is cleaner sound while moving in a breeze, without extra parts to attach.

360 Capture and the Invisible Selfie Stick

Swapping in the 360 module turns the camera into a true 360 device. Two lenses each capture significantly more than 180 degrees and the images are stitched together afterwards.

The stitching workflow is simpler than it sounds. The mobile app connects over Bluetooth and can produce finished clips automatically using preset AI shots, which can then be reframed. The desktop software offers more control, with keyframes that let you pan and zoom through a shot and export a smooth moving clip. The 5.7K resolution matters here, because zooming in during reframing keeps more detail intact.

Mounted directly on the long selfie stick, the camera edits the pole out of the frame entirely, which is why it is called an invisible selfie stick. The result looks like a camera following the rider from a distance, and the same setup can be extended behind the bike for an unusual, video game style angle.

Things to Consider Before Buying

The modular system is the main thing to weigh. It delivers flexibility, but it also means more separate pieces to keep track of and to click together correctly before a ride. The waterproof rating applies once the camera is assembled in its cage, so that housing is part of the setup rather than an optional extra.

Accessories are a meaningful part of the cost of ownership. There is a long list available: a hot shoe mount, a rubber lens cap for the 360 lens, a very small microphone adapter for external audio, spare battery bases for longer days, and the bike bundle of clips and clamps. The camera does accept existing third party action camera mounts, so anyone with a mount system already in use can carry it over.

Battery capacity on this model is about 21 percent higher than the previous generation, which is a modest rather than dramatic gain, so carrying a spare battery base remains a sensible habit for long days out.

Buying Advice

If you want one compact camera that can shoot standard 4K action footage and full 360 footage, the ONE RS covers both without needing two devices. The strength of the package is versatility, and it is the single word that best describes what the two modules deliver together.

Consider which lens you will actually use most. Riders who mainly want conventional ride footage will get the most from the 4K module and its larger sensor, while anyone drawn to the reframing freedom and the invisible selfie stick effect should plan around the 360 module and the editing workflow it requires.

Existing ONE R owners have the least risk here, since the new parts work with the older camera and the upgrade can be spread over time. New buyers should factor in the accessories they want, particularly a spare battery base and a microphone adapter if clean voice audio matters for the kind of footage they plan to shoot.

Conclusion

The Insta360 ONE RS is a well built, genuinely versatile action camera. The modular design is more than a gimmick: it changes what the camera can do without adding bulk to a ride, and the interchangeable parts keep the system open to gradual upgrades.

Real time stabilization, improved processing, and the audio changes with the built-in windshield all point to a camera that has been refined in the places that matter for shooting while moving. For anyone who wants both a standard action camera and a 360 camera in one small package, this is a compelling option worth a close look.
