DPreview tested the new TG-5 and concluded:
The Olympus Tough TG-5 stands alone in its ability to stand up to the elements and get you photos in situations where no other camera could (or situations where you simply wouldn’t be willing to bring a dedicated camera at all).
And the TG-5 doesn’t feel like just a tool to use because you need it; it’s genuinely fun. It’s responsive, handles great, has a decent amount of controls and a reliable ‘auto’ mode for when you hand the camera off to your friends. It’s practical in that it also offers USB charging, so you can use any USB power bank to charge it up off the grid, and then you can Wi-Fi transfer images to your phone for easy sharing without lugging a laptop along.
