What is a Global Shutter and Why is it so Important?

A camera's shutter mechanism controls the time during which it is recording light. Until now, mirrorless cameras have had either a mechanical shutter, an electronic shutter, or both. A global shutter records every pixel at exactly the same time. It is the most like turning a light 'on' and 'off.'

The type of shutter affects the maximum flash synchronization speed. With a global shutter, the camera can sync with the flash at any shutter speed - giving you total creative control over your image. This is amazing news for underwater photographers, as we rely so heavily on strobe-lit photography to bring out the color and detail that's obscured as light passes through water.
