Will half-pressing the shutter button hurt the camera?

Category: Leisure/Hobby>>Photography

Problem description:

I am more accustomed to half-pressing the shutter button to take pictures, because this can both capture pictures and prevent shake. , and you can also take pictures after looking at them accurately, and the photo effects will be good. But one day my friend saw me taking pictures like this with her camera and said something to me. She said that she had to adjust the shutter to capture the picture. She also said that half-pressing the shutter would affect the camera. I wonder if it is really harmful to the camera. Please help me. Guidance!

Analysis:

The poster’s statement that half-pressing the shutter button can prevent shake is completely correct. In fact, many professional photographers recommend that you hold the camera twice Press the shutter button (traditional optical cameras mostly use mechanical shutters, and the shutter button is generally tight and will shake significantly if pressed once). Today's camera shutter buttons are lighter, which greatly reduces artificial vibration when shooting.

But the time when you press the shutter halfway should not be too long. If it's a snapshot, you don't have a lot of time. For some cameras with autofocus and programmed autoexposure, you must press the shutter halfway before taking a picture so that the camera can obtain the shooting data. However, the half-pressing time should not be too long. Firstly, it wastes time and battery. Secondly, the shutter is a component that will wear out. Pressing the shutter too long unnecessarily is of no benefit.

So some cameras will start collecting data (focal length, brightness) when you put your hand on the shutter button, which also avoids the need to press the shutter halfway.
