Best Action Cameras Under $300

The Osmo Action 4 is the best low-light and best vlog-friendly action camera at this price tier. The 1/1.3" sensor pulls noticeably cleaner footage in dim conditions than the GoPro Hero 12 Black's smaller sensor, and the dual touchscreens make it the obvious choice for selfie-style work. The 18m waterproof rating beats every other pick here — useful for snorkeling, kayaking, and beach use. Trade-offs are a lower max resolution (4K vs 5.3K) and a thinner third-party accessory ecosystem.

The X3 is the category-different pick. Where the GoPro Hero 12 Black and DJI Osmo Action 4 capture flat video and require you to compose the shot live, the X3 captures the entire sphere and lets you frame the shot in post. The invisible-selfie-stick effect (Insta360's signature trick) creates drone-like third-person shots that nothing else in this round-up can match. The catch: 360 footage is editing-heavy, and the X3 isn't as sharp in single-lens 4K mode.

The Hero 11 Black Mini is the rig-mount specialist. Smallest GoPro form factor, same 5.3K60 and HyperSmooth stabilization as the Hero 12, with two built-in mount fingers that skip the standard GoPro frame. Best for situations where you'd never look at the screen anyway — chest mounts, helmet mounts, drone undersides. Trade-offs: no screen, no removable battery, and discontinued production means stock won't last forever.

The Brave 7 is the budget pick that hits the price floor without giving up the basics. Dual screens, 4K30, EIS 2.0, and IPX8 waterproof rating at $150 is a hard combination to find. The trade-offs are predictable: stabilization is less smooth than GoPro's HyperSmooth 6.0, color science is less natural than DJI or GoPro flagships, and the cadence of firmware updates is slower. For first-time action cam buyers or backup-camera use, it's a reasonable value.
