A lens controlling apparatus (112 to 114, 126) is disclosed which is capable of preventing an execution of irrelevant AF control in a combination of TV-AF method and an AF method other than the TV-AF method. The lens controlling apparatus (112 to 114, 126) comprises: a first signal generating section (112, 113) for generating a first signal showing a contrast state of an object image on the basis of a frequency component of a signal by using an image-pickup element (106) for photoelectrically converting the object image; a second signal generating section (126) for generating a second signal by a focus detecting method for detecting information corresponding to an object distance; and a controller (114) for selectively performing a first focus control operation based on the first signal and a second focus control operation based on the second signal, and for selecting the second control operation in a case where the change amount of the first signal is larger than a first predetermined amount and the change amount of the second signal is smaller than a second predetermined amount.
