PURPOSE:To control focusing with simple constitution by setting the focusing ring of a lens at a specified position previously set by an autofocusing mechanism when photographing is executed by using a stroboscope. CONSTITUTION:Image light formed into an image on the image pickup surface of a soild-state image pickup element 2 through a photographing lens 1 is converted to an electric image-pickup signal by the element 2. The image-pickup signal is converted to a specified video signal by an image-pickup signal processing circuit 3 and supplied to a recording circuit 4. In such a case, the focusing of the photographing lens 1 is performed by turning the focusing ring attached to the photographing lens 1. When photographing is executed by using the stroboscope, the focusing ring of the lens 1 is set at a specified position previously set by an autofocusing mechanism. Thus, the arrival distance of the light from the stroboscope becomes short and the focusing ring is controlled to obtain a focusing position which is adjusted to the arrival distance of the light.
