Olympus OM-D hands on review
Olympus OM-D – Live Bulb
A genuinely astonishing new feature of the Olympus OM-D is the Live Bulb setting. If you've ever been frustrated by the inexact science of setting a long exposure to capture something like fireworks, you'll love this. Press the shutter button to start the exposure and you'll see the picture gradually exposing on the screen's Live View, so you can see when you've got the shot right and can stop exposing.
