I took some footages of my friends, co-workers, and my nephew with my XH-A1. They are shot in different light settings, and all in auto-focus mode. One thing I noticed about all three videos is that I don't really have a very clear picture. What I want is a crystal clear picture. The videos that I took are a little fuzzy as if there is constant mist between the people and the camera. Is there anyway I can shoot crystal clear videos with what I have?
