Claim Text:
1. A control apparatus comprising: a first focus detection processor configured to perform focus detection by a phase difference method based on an image signal obtained from an image pickup element; a second focus detection processor configured to perform focus detection by a contrast method; and a control processor configured to perform focusing, wherein the control processor is configured to: perform the focusing, in a first mode, by using a detection result of the first focus detection processor, and perform the focusing, in a second mode, by selectively using one of the detection result of the first focus detection processor and a detection result of the second focus detection processor according to lens information, wherein the first mode is a mode in which the focusing is repeated, and the second mode is a mode in which a lens is stopped after the focusing, wherein the control processor, in the second mode, is configured to: perform the focusing by using the first focus detection processor when the lens information is first information, and perform the focusing by using the second focus detection processor when the lens information is second information, wherein the first information is information indicating that a lens apparatus has a predetermined in-focus accuracy for the focus detection by the phase difference method, and wherein the second information is information indicating that the lens apparatus does not have the predetermined in-focus accuracy for the focus detection by the phase difference method.
