专利汇可以提供Camera专利检索，专利查询，专利分析的服务。并且PURPOSE: To easily take a photograph in focus by alternatively switching and positioning a normal lens and a macro lens on a photographing optical path with a stop which demarcates a stop aperture for the normal lens and a stop for the macro lens whose aperture is smaller than the former one.
CONSTITUTION: The macro lens 14 is fitted in front of the stop aperture 24 provided on a lens holder 23 and the normal lens 27 is fitted in front of the stop aperture 26 provided adjacently to the stop aperture 24. The stop aperture 24 deepens the depth of field of the lens 14 and the aperture thereof is made small in order to prevent over-exposure at the time of photographing with strobe light. By operating a switching knob 16, the holder 23 rotates counterclockwide by resisting against the energizing force of a toggle spring 41 and a sector part 30 abuts on a stopper 37, then the holder 23 is positioned and fixed between the spring 41 and the stopper 37. Thus, photographing magnification is easily switched and a beginner can easily take a photograph in focus.
