Abstract:
1. An image pickup system comprising: a lens apparatus including a focus lens; an image pickup apparatus configured to perform image pickup through the lens apparatus; an operating part configured to be operated to instruct a movement of the focus lens; a controlling part configured to perform focus position control to move the focus lens to a position corresponding to an operation amount of the operating part; a ranging part configured to detect an object distance in each of plural ranging areas included in an image pickup region; a determining part configured to determine a distance range where the object distances detected in the plural ranging areas are distributed; and a changing part configured to change a relationship between the operation amount of the operating part and the position of the focus lens in the focus position control according to a determination result by the determining part, wherein, when defining the distance range where the detected object distances are distributed as a first distance range, and defining a distance range different from the first distance range as a second distance range, the changing part is configured to change the relationship between the operation amount of the operating part and the position of the focus lens such that a change amount of the position of the focus lens with respect to a change amount of the operation amount of the operating part in a first focus lens movable range corresponding to the first distance range is smaller than that in a second focus lens movable range corresponding to the second distance range.
