Smartphone cameras are really, really good. So it takes a compelling case to want to carry around another. Insta360's Go 2 makes a case. Just slightly larger than an AirPods Pro case, it can capture 1440/50 footage with a 120º field of view and uses a six-axis gyro to keep everything smooth. It's also IPX8-rated for water and weather resistance and can run for up to 30 minutes on its own or up to 150 in the included charging case.
