Why do photographers like to use the viewfinder instead of the screen?

My actual feeling is that for SLR and paraxial cameras:

1. LCD pixels are too low, and the color and brightness are greatly affected by the environment. Optical viewfinder is the restoration of real scene, which can be replaced by ten million pixels, and the color brightness is what you see is what you get. It is convenient for photographers to control images.

2. Speed LCD framing, even now his delay is unbearable for news and sports reporters.

3. Composition control. The optical viewfinder of a SLR camera is surrounded by black, so you can focus on the scenery when taking pictures. This advantage is generally not realized, but when you use the optical viewfinder, you will find it a bit awkward to use LCD for composition.

4. Some of Canon's film SLR have eye control focusing function.

In fact, shooting with an optical viewfinder can greatly improve the stability of the camera, thus improving the clarity of the photo.

6. Some sexual friends are cool, such as me, hehe.
