The top shutter speed of 1/8000th in the OM-D EM-1 is useful when you need it, but keep in mind you will need good light or the ISO will need to go up too. When shooting such subjects, you probably want to fire in continuous 10 frames per second mode. The good thing is that the EM-1′s buffer is now higher, allowing a burst of 40 continuous raw shots at 10 fps before it slows down to catch up. Actual numbers, of course, depends on the speed of your SD card.
Over the years I have used a E-3, E-5 and EM-5 to cover the annual Rainforest 4WD Challenge held during the monsoons. It is rated as one of the ten toughest motor races in the world. The Olympus cameras and lenses have never failed me in heavy torrential rain, mud slides and floods.
The same 12-60 mm lens I am using for both the test shots here fell into the river with the E-3 body a few years back. By the time, I climb back down from the cliff to recover it, it was lying submerged for at least a good two minutes. Suffering some initial optical viewfinder fogging, it dried out to work as normal for several years more. When Olympus states a body and lens combo is weather resistant, I know they mean it.
In a recent session with the EM-5 under heavy rain, the play function stopped working. It recovered by itself after it dried out. See the thunderstorm picture here.
