If you see the Canon EOS R5 as a pro stills camera with some impressive video features, then it's one of the best the photography giant has ever made. There's no doubt it has video limitations compared to a rival like the Sony A7S III, particularly for shooting longer clips. But for anyone looking to shoot mind-blowing stills in almost any situation, whether that's wildlife or studio work, it's a hugely impressive achievement.
Particularly worth of mention is the EOS R5's autofocus, which offers very accurate and reliable subject-detection and tracking – particularly when its comes to people or animals. You also get a superb 5.76-million pixel EVF, a body design that will be comfortably familiar to those coming from DSLRs, and the ability to shoot bursts at 12fps with the mechanical shutter (or 20fps with the electronic equivalent). The video performance, while limited to relatively short bursts, remains superior to the likes of the Nikon Z7 and Sony A9 II, too. With a growing collection of (albeit pricey) RF lenses, the Canon EOS R5 is the next-gen mirrorless camera that pro photographers have been waiting for.
If you're looking for a tough, waterproof backup camera that you can stick pretty much anywhere, then the Hero9 Black is the best option around right now. Its new front-facing LCD is a boon for vlogging, while its 5K video mode captures more detail than any other action camera. That said, it's all of the Hero 9 Black's little software tricks that really elevate it above the Hero 8 Black and DJI Osmo Action. Its HyperSmooth stabilization now works in any video resolution or frame-rate, while features like TimeWarp and HindSight (which lets you capture that happened 15-30 seconds before you hit the shutter) are genuinely useful creative tools. If you don't need the Hero 9 Black's versatility or front screen, then the Hero 8 Black remains better value. It also currently has issues like a slightly unresponsive rear touchscreen, which GoPro is promising to fix with firmware updates. But if you're looking for a brilliant B-camera, or a main camera for adventure sports, then it's hard to beat the Hero 9 Black.
