With this camera you don't really need a tripod.
Try these settings...
Servo AF - On
AF Mode - Continuous
AF Frame Mode - Center or FlexiZone
ISO - Fixed at 80 or Auto (noise can make an image appear not sharp).
Aperture Priority set to lowest number - there's plenty DOF.
Image Size - Large Super Fine
Open original JPG and Save As uncompressed tiff or a psd file.
Sharpen image as last step in photo editing.
