SLR takes a large number of data pictures in a short time, such as taking nearly 10,000 pictures a day. Is it harmful?

1 000 is really a heavy load. You should know that many photographers' cameras are about 1-30000 when they retire. If it is 24 hours, they will take a photo every 8.64 seconds. If they work for 8 hours, they will take a photo every 3 seconds. Unless it is time-lapse photography, it is difficult to have such a large lens amount. A SLR camera in good condition should be fine for one day. Most importantly, however, this intensity of use will not last long. The nominal shutter life of mid-to high-end cameras is generally 10- 15000. If it exceeds this number, it may not be broken immediately. Generally speaking, the shutter may be inaccurate or fail occasionally, because many moving parts inside the SLR, except the shutter assembly, mirror, drive motor, etc., will age with time and lose accuracy.
