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).
Is GoPro a good camera?
Waterproofing is important to consider if you'll be recording footage underwater or even around water. Some waterproof cameras can go deeper than others, and some have built-in waterproofing so that you don't need to think about extra housing. And if you're already invested in a system, like GoPro, which uses a proprietary mount, then sticking with what you've got can help save money on extra accessories.
Fortunately, we are now blessed with several cameras and great underwater housings that meet these criteria for the "best underwater camera". Whether you are looking for the best underwater camera for scuba diving or snorkeling, we are sure you will find it here. I'd also like to point out, that we define a compact camera as a camera with a fixed lens.
