Abstract

There is provided a focus adjustment apparatus. A first obtainment unit obtains a focus degree in a predetermined region of a shooting range. A driving unit drives a focus lens in response to an operation unit being operated. A movement amount of the focus lens per unit of an operation amount of the operation unit during the driving is lower in a case where the focus degree is greater than a focus threshold than in a case where the focus degree is lower than the focus threshold. The focus threshold is higher in a case where the focus lens is moving in a direction that increases the focus degree than in a case where the focus lens is moving in a direction that reduces the focus degree.
