ABSTRACT:
A camera including a variable illuminating angle strobe device, includes a zoom lens which has a group of variable power lenses for stepwise or successively varying the focal length; a light emmitter which has a condenser lens, a light emitting tube and a reflecting shade and which is movable between a received position in which the light emitter is received in a camera body and a projected position in which the light emitter projects from the camera body; and an illuminating angle varying mechanism which varies a relative position of the condenser lens, the light emitting tube or reflecting shade in accordance with the change in the focal length of the zoom lens to vary the illuminating angle, regardless of the position of the light emitter.
