according to this review [http://www.imaging-resource.com/PRODS/omd-em5/omd-em5A.HTM]--that camera is "weather sealed " against dust and splashing, but not immersion. In the video, the photographer states that you would need to use a waterproof lens. Whether or not I would do that shoot with that camera would depend on what the manufacturer defined as "splashing". Because the video seemed to be a successful test on that occasion would not convince me. I would feel better if I got caught in the rain during a shoot, but I would NEVER intentionally place a camera in water, regardless. Doesn't really make sense to me.
It's about time Olympus started showing their waterproof cameras in action... it's just a few years too late.
About 7 or 8 years ago Olympus would demonstrate their waterproof DSLR (e3) at trade shows by shooting runway fashion models while pouring water all over the camera. As a matter of fact, some of the water splashed on the guys stage microphone and shorted it out so we couldn't hear him speaking, but the camera kept on going.
Then they'd say "How do you clean an E3? Just wash it off" again pouring water all over it.
If Olympus would have done similar demonstrations on TV and print ads, I have no doubt they'd still be a major contender in the DSLR market today, but their marketing sucks so very few consumers ever knew about it's ruggedness and waterproof build.
I got caught in the rain about a month ago with my T1i. I was shooting at a nature preserve and was a 2 miles or so from the car. Not much I could do but walk and shoot my way out. The thing still works great, I haven't had a problem with it since I got it 3 years ago. +25000 images and running strong.

Sure, why not?
If your gear's sealed enough to take it. I've had my D300s and 70-200mm f/2.8VR & 300mm f/4 AF-S out in pretty decent rain before now and it's never been a problem. I've even fallen in a river with my D100 and it got a damn good splashing (although not submerged).
I own an OMD and did a photowalk in the rain about a month back. While standing in a group with my E-M5 hanging around my neck I noticed people looking at my camera getting soaked. Finally one woman to my left says " Aren't you worried about your camera getting ruined?" I replied " Nope, it's weather sealed" She then said " so is mine but I baby it" and she pulled open her coat to show me a 7D I just smiled and said. " well I've put my Olympus gear through some nasty stuff and the weather sealing has never failed. So I trust it."
