What is your camera shutter count? It's the number of actuations on the shutter mechanism on your camera – in other words, it records the number of shots a camera has taken.
Accordingly, it's also a representation of the life of your camera. In the same way that an odometer measures the miles racked up by a car, the camera shutter count measures the "mileage" on your body. And this is important because, like car motors, mechanical shutters have a life span.
