Although Pentax autofocus is lacking in speed and tracking ability, it is very accurate if single point is used without recomposing . For that reason I always use the shutter button to focus and rarely recompose. With the K-1 I almost always have enough pixels to allow altering of the composition by cropping. I do try to pre-position my focus point to maximize picture area.
