ªAuto focus
Auto focus automatically moves the focusing lens forward and backward inside the movie camera to bring the subject into focus.
Auto focus has the following characteristics. ≥Adjusts so that the vertical lines of a subject are
seen more clearly.
≥Attempts to bring an object with higher contrast into focus.
≥Focuses on the screen centre only.
Due to these characteristics, auto focus does not work correctly in the following situations. Record pictures in the manual focus mode.
Recording a subject with one end located closer to the movie camera and the other end farther away from it
≥As auto focus adjusts at the centre of an image, it may be impossible to focus on a subject that is located in both the foreground and background.
Recording a subject behind dirty or dusty glass
≥The subject behind the glass will not be focused because the focus is on the dirty glass.
Recording a subject that is surrounded by objects with glossy surfaces or by highly reflective objects
≥The recording subject may become blurry because the movie camera focuses on the objects with glossy surfaces or on highly reflective objects.
Recording a subject in dark surroundings
≥The movie camera cannot focus correctly because the light information that comes through the lens decreases considerably.
Recording a fast-moving subject
≥As the focus
Recording a subject with little contrast
