Will the smooth reflection of Sony app shorten the service life of camera shutter?

1. Any camera (including film camera, digital camera and mobile phone) has a shutter life. The life of the shutter is related to the mechanical accuracy of the shutter, the opening and closing time accuracy of curtains (including electronic curtains), and the number of times the sensor receives light. Shutter life affects the service life of the camera. Some SLR's indicate the number of shutter life in their parameters, while non-reflex (micro-single), portable machine (card machine) and bridge machine (telephoto machine) do not indicate the number of shutter life, but the shutter life exists objectively;

2. Sony Smooth Reflection APP has three options: Lo, MID and Hi, which are used to control the smoothness of imaging. However, no matter what kind of file is used, the camera takes multiple photos continuously, and it is synthesized by the built-in software to achieve a smooth effect. Among them, Lo took 32 shots, MID took 64 shots, and Hi took 65,438+028 shots, which means that the mechanical movements of the shutter were 32,64 and 65,438+028 shots respectively. Because the shutter life of the camera is fixed, ranging from 300,000 times, 200,000 times, 1 0.5 million times,110,000 times, Sony Smooth Reflection APP will accelerate the mechanical movement times of the shutter, so it will shorten the service life of the shutter;

3. Although Sony Smooth APP will affect the shutter life, it can prevent the sensor from aging when taking photos with the same effect. The working principle of digital sensor is to convert the light elements collected by the lens into electrical signals, which will inevitably produce thermal noise, and long-term thermal noise will aggravate the aging of the sensor. Ordinary methods of shooting smooth images all rely on long exposure, which is generally more than 10 second, and continuous photoelectric conversion work is more harmful to the sensor. Although Sony APP takes many photos at a time, the exposure time of each photo is very short, and the transient photoelectric conversion has little influence on the sensor, so it is helpful for the aging of the sensor.

4. From the perspective of shutter assembly and sensor assembly, the cost performance of replacing shutter assembly is higher than that of replacing sensor assembly, so Sony APP is cheaper and more convenient than ordinary long exposure when taking photos of smooth subjects.
