I use shutter priorty on everything I shoot and watch my f/stop setting and adjust accordingly. Depending on what I am shooting, I don't want the camera changing known needed speeds on me. Focus will always be there normally but a slow speed to some will appear like lack of sharpness in their shots. I shoot horse shows and still shoot everything from a mono-pod with My selected speed to capture it. If my f/stop starts to open too much, I adjust my ISO slightly. If I shoot still shots on a tri-pod, I will than use aperture priorty. Syl Z.
