GoPro has released some new firmware for the Hero 9 Black, which could resolve some of the slight issues we found with its touchscreen interface and auto exposure – we’ll update this review as soon as we’ve tested it fully.
The two biggest upgrades are its new sensor and front display. That new 23.6MP sensor shoots 5K video that does deliver slightly more detail than the Hero 8 Black, in the right conditions. But perhaps the bigger benefit is to its electronic stabilization, with the Hero 9 Black able to provide HyperSmooth Boost – GoPro’s strongest stabilization – in all shooting modes. This makes it a top performer for those who demand high-quality 4K (and 5K) video.
