Ask all photographers for help. Canon 70D lens loves Guo Xuwei. It is mainly used to shoot portraits in RAW format. What's with the noise?

The higher the sensitivity, the more noise, which is normal. If you want less noise, lower the ISO to 100-200. If the light is not enough, you can use a flash or a reflector. No matter how good the lens is, the light is not enough. The shutter speed of 200mm lens should be at least higher than 1/200s. If you have a bad expression when taking a stage photo, it's too early or too late to capture it. This can only be practiced more.
