Camera having a built-in strobe and lens for use therewith |
摘要 |
A strobe built-in camera includes a camera body having a strobe built therein and at least one photographing lens to be detachably mounted on the camera body. The camera comprises a strobe use-warning device for warning unsuitability of use of the strobe in case of the the photographing lens mounted on the camera body reduces a quantity of light emitted from the strobe to a value less than a correct quantity of light to be irradiated upon an object, or that a spreading zone of the light from the strobe is narrower than a field of view of the photographing lens. Therefore, photographing under inappropriate photographing conditions is prevented and superfluous use of films can be avoided.
