摘要: PROBLEM TO BE SOLVED: To provide an imaging lens having a wide angle of view providing photographing 160 degrees or more, and excellently correcting chromatic aberration magnification while being compact.SOLUTION: The includes, in order from the object side to image side, first group negative refractive power, aperture stop, second positive power. G11 G12 G13 G21 power at least one aspheric surface, cemented made up G22 G23 Abbe number arranged closest entire system, focal distance group, are set appropriately.
