Simpli fy your focus
Accurate focussing is vital, but there are simply too many options with most cameras. I like to simplify everything, including my focussing settings. I like to use Continuous-servo AF (AF-C) and single-point focus through the shutter release button. I move the focus over the part of the image I want in focus, such as the eyes in a close-up portrait. If the focus point is outside of the sensor area I can focus and recompose by hitting the focus lock button with my thumb. This will cause the camera to behave as if I have selected the Single-servo AF (AF-S) setting. The only variation I make from this is to use one of the more dynamic area AF area modes if shooting a fast-moving subject.
