Insta360's Go 3S action camera has received an intriguing update with the introduction of the Retro Viewfinder accessory. This accessory transforms the Go 3S into a handheld shooter, reminiscent of classic film cameras, offering a unique framing experience. However, the execution has its shortcomings, and the accessory's functionality is often frustrating. The Retro Viewfinder's limited viewing angle and horizontal image flipping make it challenging to frame shots accurately. Despite this, the accessory is available for purchase, either separately for $47.99 or as part of a bundle with the Go 3S for $299.99. The bundle includes a 64GB version of the action cam, providing a cost-effective option for those already invested in the Insta360 ecosystem. The Insta360 Go 3S itself is an excellent camera, but its wide field of view doesn't align with the Retro Viewfinder's design, leading to inaccurate previews of captured content. The accessory's battery life is also limited, requiring frequent charging during extended use. Changing settings on the Retro Viewfinder necessitates a direct Wi-Fi connection to a smartphone, which can be cumbersome. While the Retro Viewfinder adds a novel dimension to the Go 3S, its execution falls short of perfection. The accessory is a clever idea, tapping into the popularity of retro cameras, but it could benefit from further refinement to provide a seamless and intuitive framing experience. For those seeking a more comprehensive solution, the bundle with the Action Pod offers a more convenient and feature-rich experience, making it a better long-term investment.
