1. An imaging apparatus comprising:
- a range-finding region arrangement unit which arranges range-finding regions of which region sizes are different by hierarchizing thereof;
a range-finding region selection unit which selects the range-finding region in a predetermined order from the arranged range-finding regions; and
a control unit which performs a focusing operation by generating an evaluation value which denotes degree of focusing with respect to the range-finding regions which are selected in the range-finding region selection unit, and controlling a position of a focus lens based on the evaluation value.
