In the past, video cameras did not have LCD monitors attached to them. Focusing a shot was dependent on the use of the viewfinder. Today however, the viewfinder is becoming less and less a functionary part of video cameras. People have been more reliant on their LCD monitors. What people don’t realize is that a viewfinder is a more accurate tool in focusing shots.
LCD monitors provide a wider view. Sometimes it takes away the focus on the actual object of the shot. Whereas a viewfinder is more centered. Give the LCD a rest and test the difference with a viewfinder.
