Picture is from a Still Capture of OM-D HD footage
Here is a real world use / test of the splash-proof feature of the Olympus OM-D (EM-5). The weather sealing means the camera is water resistant should the need arise. The riverside cleansing ritual is part of the Hindu Thaipusam Festival at Batu Caves, Kuala Lumpur, Malaysia.
There was slight fogging of the viewfinder (at one corner) after the shower but it dried out after about 10 minutes. Try / use under such conditions at your own risk, though. Slow-mo with Edius.
