Abstract: A digital photographing apparatus is provided for performing an auto-focus (AF) function and a method of controlling the digital photographing apparatus is provided as well. The method of controlling the digital photographing apparatus includes determining whether an AF operation is about to be performed by using a deviation of image data or a vibration degree of the digital photographing apparatus; performing a preceding operation of a focus lens if it is determined that the AF operation is about to be performed; and performing a post operation of the focus lens when a first shutter-release button input is received. Thus, a moving distance and a frequency of changing direction of the focus lens may be reduced by recognizing a behavior pattern of the user, and thus, an AF operating time (i.e., AF operating time after the user pushes a shutter) may be reduced.
