发明名称 Camera with strobe and lens for use therewith
摘要 A camera having a camera body with a strobe built therein and at least one photographic lens that is detachably mounted on the camera body. The camera has a strobe use-warning device for warning of the unsuitability of the use of the strobe in the case where the photographic 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 for irradiating an object, or where a spreading zone of the light from the strobe is narrower than a field of view of the photographic lens. This prevents photographing under inappropriate photographing conditions and the superfluous use of film.
