The maximum sequential shooting speed indicates the highest number of frames per second (fps) that the camera is capable of capturing when the shutter button is pressed continuously. This value is a key parameter especially when photographing moving subjects such as athletes, animals or vehicles, where a higher frame rate increases the chance of capturing the ideal moment. For interchangeable lens cameras (ILC), i.e. mirrorless cameras and SLRs, the maximum speed quoted refers to the sequential shooting speed of a mechanical shutter. Electronic shutter speeds may allow for higher shooting speeds in these devices, but may cause an undesirable rolling shutter effect. The achievable sequential shooting speed also depends on the specific camera model, the lens used and the current settings.
