About cable release:

1, cable release is a kind of camera that can control the camera to take pictures, prevent the camera surface from vibrating and destroy the integrity of the picture.

2. The development of cable release: the early "pneumatic" cable release was just a balloon connected with a catheter, and the pressure generated by squeezing the balloon pushed the remote shutter to achieve the purpose of taking pictures; Although this method is simple and low cost, its reliability is poor. Later, a hollow steel wire cable releaser was developed, which was closely combined with the spiral hole on the shutter of the fuselage, making the performance of the cable releaser more reliable. With the large-scale electronization of traditional cameras, even entering the era of digital cameras, the development of cable releaser is moving from single function to more complex application. Today's cable release not only triggered the shutter; Including long-time photography, interval photography, timing photography, etc. using the B shutter lock function. Even in many indoor photography, in order to avoid the pressure of the model directly facing the camera, many photographers are used to staying away from the camera body, directly guiding the model's movements, and then releasing the cable to capture the instantaneous picture.

3. Cable release types: There are many common cable releases in the market, such as "mechanical cable release", "electronic cable release" and "high-end special cable release". This proves that our products are widely used, and almost all photographers will use them. In the camera, the socket for cable release is also different from USB. It can be said that the cable-released connector is the main input port and the only input end of the external auxiliary accessories of the camera in the future.
