GoPro Hero7 Black £349 / stuff.tv/Hero7Black
This is basically the excellent Hero6 Black (a five-star action cam that cost £500 at launch) with a bunch of improvements added – the most useful of which being the incredibly effective HyperSmooth image stabilisation, which has a huge impact on video quality. It’s great to see a company like GoPro continue to innovate in ways that are genuinely valuable to its main customer base, and the Hero7 Black is the best camera it’s made in years
