The advantages and disadvantages of LCD viewfinder

There are several obvious advantages of the LCD viewfinder:

First, the image we see through it is the image to be imaged, and the parallax is very low, what we see is what we get;
Second, now many digital camera's LCD is designed to be rotatable, so that the digital camera will have more viewing angle, and it can be very intuitive to achieve self operation.

The disadvantages of the LCD viewfinder are obvious.

First of all is the power consumption. For a long time, the LCD viewfinder is a power hungry digital camera. It will greatly shorten the working hours of digital cameras for a long time. Fortunately, now the new digital cameras have adopted a large number of low-temperature polysilicon LCD screen, so the power consumption of the LCD viewfinder has been significantly improved, but calling it "power hungry" is still not excessive.
Second, in the intense sunlight, the LCD viewfinder display will be greatly affected, and you need to use your hands or other things to hide the light before you can see it clearly.
Finally, when the ambient light is too dim, the LCD viewfinder also has problems of dim image and unfavorable viewing.

LCD viewfinder requirements

The LCD determines the size of his overall consumer groups, especially for the elderly or eyes from time to time good people, LCD means they can more clearly see the captured images, but also indirectly makes them for photography to generate interest, presumably this is one of the important factors of large businesses have launched the LCD view screen.
