摘要:
An ophthalmologic photographing apparatus includes an optical system, a pedestal, an auxiliary lens configured to be able to be inserted into and retracted from the optical system, a focusing lens, a focusing lens driving unit configured to move the focusing lens along an optical axis, a pedestal position detection unit configured to detect that the pedestal is away from the subject's eye by a predetermined distance, an auxiliary lens insertion detection unit configured to detect that the auxiliary lens is inserted into the optical system, a storage unit configured to store a position of the focusing lens, and a control unit configured to cause the focusing lens driving unit to move the focusing lens to a predetermined position stored in the storage unit based on outputs from the pedestal position detection unit and the auxiliary lens insertion detection unit.
