When shooting a concert with a camera, how much damage does the LED laser light and various flashes do to the SLR camera?
It won't hurt. When the SLR camera is not shooting, the light will not directly shine on the photosensitive element, and it will only receive the light when the shutter is open. Moreover, this kind of light does not have the ability to damage the photosensitive element in intensity, and it will only be damaged if it is exposed to the sun for a long time.
