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.
