A video camera with a microphone having controllable directivity characteristics to an object in synchronism with focusing of the video camera to the object. The microphone is an optical microphone (300) comprising a diaphragm (2) vibrating with sound pressure, a light source (3) for irradiating the diaphragm (2) with a light beam, a photodetector (5) for receiving part of the light beam reflected from the diaphragm (2) and outputting a signal corresponding to the vibration of the diaphragm, a circuit (13) for driving the light source (3) by supplying a predetermined current, and a negative feedback circuit (100) for supplying a part of the signal outputted from the photodetector (5) to the light source driving circuit (13) as a negative feedback signal. The directivity characteristics of the optical microphone (300) are controlled by varying the magnitude of the negative feedback signal with a zooming signal indicative of the zooming amount of the video camera with respect to the object.
