Compared to the Olympus Tough TG-6, the Nikon COOLPIX can capture higher resolution images with more versatile zoom range. But the TG-6 has a brighter lens (f/2.0 versus f/2.8 in the Nikon), as well as the ability to shoot photos with higher ISO, so it's better in low-light photography. The Olympus also has higher burst-capture capabilities than the Nikon (20 versus 7 frames per second).
Ultimately, your choice in action camera should come down to performance and ease of use. We've filmed hours of footage with many of the major contenders to determine where each device stands in the field. Some excel in all manner of extreme situations, while others can fall apart underwater or once the sun goes down. And what good is an action cam if it's not built for action?
What's the best helmet camera?
The latest flagship GoPro model is our favorite action camera available right now. A key difference from its predecessor (and especially the less expensive Hero7 Black) is that there are fold-out feet, giving you the advantage that the camera mount is now built in. Furthermore, you can accessorise the Hero8 Black with a new series of bespoke optional extras called Mods – we particularly like the Display Mod, which adds a second monitor that is perfect for vloggers, but there are plenty of others, including a Media Mod for improving the production value of your videos, and a Light Mod LED light too. These add-ons cost you more – but if you are looking for the very best action camera, and the best GoPro for image quality and features, then the Hero8 Black is it.
