CameraLabs tested the new Olympus TG-5:
There isn’t a better rugged waterproof compact around than the Olympus TOUGH TG-5. Like all great cameras it gets the basics right – a bright, good quality 25-100mm f2 – 4.9 lens paired with a quality 12 Megapixel sensor and high performance TruePic VIII processor. It builds on that with a great set of features and shooting modes, including Pro capture continuous shooting, 4K video, RAW support, and superb macro modes. Finally, it provides the control you need to make the most of those features, whatever the environment. The only downside is the poor performance of the movie continuous AF.
Also Photographyblog reviewed the new Olympus camera:
The Olympus TG-5 is certainly one of the better toughened-construction cameras we’ve used and one that hasn’t been unduly compromised by the fact that it has indeed been reinforced. Whether you think it’s worth spending £400 on what is largely a point and shoot digital camera, albeit one ready for battle, will depend on your specific requirements. But it is a capable, consistent performer, despite the small sensor.
