Insta360 has unveiled one of the craziest camera kits for 2026 – a ‘Retro Bundle’ edition of its thumb-sized 4K camera, the Go 3S.

We rate the original as the best ‘small’ 4K action camera – it’s really small and can be placed in spaces that no other camera can, or rigged up for athletes and so on for a first person POV of the action.

But unlike the original, which comes with a flip-up LCD screen dock for composing shots and remote control, the retro version feels more like a Polaroid.

You get the 4K camera, which also shoots 12MP stills, in one of two colors, with a matching optical viewfinder dock instead.

The waist-level viewfinder reflects the front view for composing shots, is fully optical, and doubles as a selfie mirror.

And if it wasn’t obvious from the pictures, the camera itself has no screen, just a single button. That’s right, this is a 4K digital video camera with no screen at all, just the button – it’s as retro as digital video cameras get.

A single tap on the camera button starts video recording, a double tap takes a photo and so on, but if you need more control, that’s where Insta360’s app comes in.

The camera can still be paired with a smartphone through the Insta360 app, through which users can control the camera remotely.

And it’s still the same Go 3S, with its unique small body and video/photo prowess, just wrapped in a different skin that’s sure to appeal to analog lovers – call this the Polaroid-like camcorder!

Insta360 sells a leather case for the retro bundle, which has a different aesthetic and feels like an odd match, but it looks great on its own — you can see it in the gallery above.

The Go 3S Retro Bundle costs $300 / £279 / AU$470 for the 64GB version or $320 / £299 / AU$500 for the 128GB version. The latter feels like the obvious choice – you want as much internal storage as you can get because there’s no card slot.

If you already own the Go 3S and like the sound of the retro viewfinder, the viewfinder part can be bought separately for $48 / £46 / AU$80, which is great to see.
