The accessory repurposes the Insta360 Go 3S as a handheld camera if you can learn to master its top-down viewfinder.

The pill-shaped Insta360 Go 3S 4K action camera launched in June 2024 as an updated version of the 2.7K Go 3 that debuted a year prior. While last year’s Go Ultra introduced a redesign with a larger sensor and higher frame rates, the Go 3S has stuck around as a smaller but still very capable alternative. To broaden its appeal, the action cam is now available with a new optical viewfinder accessory for framing shots when using it as a handheld camera, but you may be better off splurging on Insta360’s more expensive dock that adds an LCD screen.
The Retro Viewfinder accessory is available today through Insta360’s online store on its own for $47.99, or as part of a new Go 3S Retro Bundle starting at $299.99 that includes the 64GB version of the action cam. That’s cheaper than the $349.99 Standard Bundle that pairs the same version of the Go 3S with Insta360’s Action Pod dock.
As with most tiny action cameras, the Insta360 Go 3S lacks a screen of its own. You can connect it to a smartphone app to see live previews and adjust camera settings, but the Go 3S is designed to be mounted where you wouldn’t be able to see a screen (like atop a helmet) where it captures nearly all the action in front of you using a wide-angle lens.
