With a few weeks of use around the world, the GoPro Hero 6 Black is becoming one of the favorite slow motion affordable cameras for all sorts of activities. While the quality is not the best out there compared to cameras like the Sony RX series, it is competitive within its price bracket. Aliasing and moire at 240fps are apparent but mostly non-intrusive for action shots. If you need it as a broadcast quality recorder then the slow-motion mode is not at the required level.
The camera does not have a 480fps mode or higher which could have been a fantastic surprise for high-speed fans. After all, GoPro had been the go-to camera for higher frame rates in the affordable category for nearly a decade. The Hero 6 Black is still an excellent option with the highly improved sensor, processing, codec, and frame rate varieties that should be able to produce anywhere from broadcast quality 4k 60p to pretty good 120 2.7k and 240fps web ready 1080p.
