Abstract: The image pickup apparatus has a focus lens that adjusts focus on a subject, an operating section (an MF operation ring) that accepts user's operation, and a focus-lens driver that drives the focus lens in response to the user's operation. The focus-lens driver drives the focus lens so that a rotation amount at the operating section, which is required for moving a focus position by unit distance, is maintained at a constant level with no regard to a subject distance.
