A lens control apparatus for controlling the position of a focusing lens includes a rotary operation member, a detector, having a rotary encoder coupled with the rotary operation member, which detects the amount of rotation per unit time of the rotary operation member by counting the number of pulses per unit time outputted from the rotary encoder, and a conversion circuit for converting a detection output of the detector into a signal indicative of the position of the focusing lens. Further, the lens control apparatus is provided with a control characteristic changing circuit for changing a control characteristic of the lens. <IMAGE> |
