The present invention is directed to an autofocus method and an image capturing system. A focusing lens is used to focus within a first moving interval in a zoom mode, and a plurality of first focusing positions and a plurality of corresponding first focusing data are recorded. An absolute maximum is determined among the first focusing data. A second moving interval is determined if the absolute maximum does not exist among the first focusing data, and the focusing lens is used to focus within the second moving interval to obtain a plurality of second focusing data. The absolute maximum is determined according to the second focusing data, wherein a second focusing position corresponding to the absolute maximum is an autofocus position. |
