Olympus is to my knowledge the only manufacturer who also offers underwater housings for their cameras directly.
Therefore it makes sense that there is a diving blog on the Olympus homepage:
With the dive blog we want to show you the latest stories and show you breathtaking places and pictures of the latest journeys of our visionaries. All travel around the world to find new,
amazing dive sites and, of course, to shoot the next unbelievable photos below the surface! Get inspired for your next trip!
