With 5K video recording capabilities, improved battery life and a new front-facing display, the Hero 9 Black could be easily 2020's best action camera, though it's bigger and pricier than before.
Using a Canon-made 45MP CMOS sensor, the new EOS R5 is able to capture 8K RAW video at up to 30p and 4K at up to 120p. Meanwhile, the EOS R6 shoots 4K video up to 60p and 1080p/120p slow motion. Pre-orders start at $3,899 and $2,899, respectively.
