A camera has a photomerry device to measure luminance of an object. The camera is provided with a strobe unit in which a strobe light is automatically emitted when the result of measurement by the photometry device is smaller than a predetermined luminance and an amount of light emission can be changed. The camera with the strobe unit includes a range finder to measure a distance of an object; a memory having a flashmatic calculation table in which F-number corresponding to the distance of the object are set according to a guide number which is used as a reference; a calculator in which a value of the guide number is changed according to a reference F-number in the flashmatic calculation table obtained by the measurement by the range finder and a desired F-number is found. The camera further includes a controller in which a strobe light is emitted by controlling the strobe unit by the desired F-number obtained by the calculation result of the calculator.
