Focus adjustment device having a control unit that drives a focus adjustment optical system to a focused position acquired first by either a contrast detection system or a phase difference detection system
A focus adjustment device comprising: a first detector 221 which detects a focused state by a contrast detection system; second detectors 222a, 222b which detect a focused state by a phase difference detection system; and a control unit 21 which controls the first detector 221 and second detectors 222a, 222b so as to detect the focused state by the second detectors 222a, 222b when detecting the focused state by the first detector 221. 展开▼
