An interchangeable lens type digital camera includes a camera main body and an interchangeable lens. The camera main body includes a control section which communicates with an interchangeable lens, and controls focus adjustment of the interchangeable lens by a hill-climbing AF system. A judgment section judges a characteristic of the interchangeable lens on the basis of communication between the interchangeable lens and the control section. The interchangeable lens includes a focus lens for performing focus adjustment. A focus lens drive section drives the focus lens. A lens control section communicates with the control section, and controls the focus lens drive section to perform focus adjustment. The control section changes a previously determined drive enabled range of the focus lens on the basis of a judgment result of the judgment section to perform focus adjustment of the interchangeable lens.
