so to summarize, your camera has three main focus modes. Single servo. Continuous server on manual. Single servo is ideal for static subjects, while continuous servo is ideal for moving subjects. Auto focus works by detecting contrast. If there's no contrast, a camera cannot focus automatically the F points in the viewfinder, the tool the camera uses to detect contrast and usually the center of points of the more accurate and responsive when deciding on your point of focus. If you're photographing an animal or a person most of the time, you should focus on the eyes. When focusing on a moving subject, try and anticipate where the subject will be when you press the shutter, turning to sharpness there is only one point of focus. That's the focus distance. Everything in front of or behind the point of focus is out of focus. But there is an area either side of the point of focus that appears sharp. This is the area referred to by the term depth of field. Now, depth of field is influenced by...
camera to subject distance and focal length. It is controlled, however, by lens aperture. Now a small lens aperture gives deep depth of field, a large lens aperture give shallow depth of field. Hyper focal distance. Focusing is a technique for maximizing depth of field for action shots and moving subjects you can employ. Focus tracking. When subject movement is predictable. Used fewer F points when subject movement is unpredictable. You'll need to use morayef points on the more unpredictable the movement the morayef points you need. But remember, using multiple F points slows down auto focus because the camera has to assess every single point when making focusing decisions, and that just slows things down. The focus tracking delay function tells the camera toe. Wait before adjusting. Focus Distance. This is used to avoid the camera refocusing on objects to obscure the main subject momentarily, when there is no clear line of sight between the subject and the camera and in low light and low contrast situations, Manual focus may be the quickest and most accurate way of focusing, and that's it for focus.
