I think Gopro Fusion is in a difference price range, at around $700. But I agree that Insta 360 One is a good comparison point. Have you used all these cameras? And what are you using the THETA for most?
Nice comparison of 360 cameras by Mic Ty on 360rumors:
And information on THETA V: Ricoh Theta V - Top 10 features; plus: comparison with other popular 360 cameras - UPDATED
Since you’re on the theta360.guide, maybe you care more about building solutions for your 360 camera. I think the THETA is exceptionally strong there with an open API and a big, energetic developer ecosystem. Plus now, there’s a whole new powerful platform to develop on with the THETA V.
Are you a developer?
