Dpreview published the full Olympus TG-6 review and concluded:
The Olympus Tough TG-6 continues to be the top waterproof camera on the market. We like its ruggedness, expandability, tracking features, and Raw support. Its lens is faster at the wide-angle end than its peers, and its macro capabilities are top-notch. Battery life is very good, assuming that you’re not hitting the GPS too hard.
