Cameras with a mechanical shutter
Mechanical shutter
— there are many types of mechanical shutters, however, in modern digital cameras, systems in the form of a pair of shutters are predominantly found. When the shutter opens, one of the curtains moves, and then the second “catches up” with it, closing the matrix. The main advantage of mechanical shutters is that when using them, the matrix always remains closed and opens only at the moment of shooting for a time corresponding to the set shutter speed (similar to how it happens in film cameras). Due to this, it is possible to avoid heating the sensor and the associated increase in image noise. On the other hand, additional mechanisms noticeably affect the weight, dimensions, cost and power consumption of the camera; when shooting fast moving objects, distortions may occur, and at low temperatures — failures and even failures. In addition, cameras with mechanical shutters are mainly designed to work through an optical viewfinder. For an electronic viewfinder or Live View mode, you either need to install an auxiliary matrix (which further complicates and increases the cost of the design), or completely open the shutters and actually shoot in electronic shutter mode, which makes the very idea of \u200b\u200b"mechanics" meaningless. But such a solution has found application in a paired type of shutter, combining mechanics and electronics.| mechanical shutter | clear | Save List |
