WIDE ANGLE LENS, OPTICAL EQUIPMENT WITH THE WIDE ANGLE LENS, AND METHOD FOR MANUFACTURING WIDE ANGLE LENS

摘要

PROBLEM TO BE SOLVED: To provide a wide angle lens whose size is small, respective aberrations are satisfactorily corrected, and optical performance is excellent, to provide optical equipment that has the wide angle lens, and to provide a method for manufacturing the wide angle lens. SOLUTION: The wide angle lens WL mounted to an electronic still camera 1 or the like includes, in an order from an object side: a first lens L1 composed of a negative meniscus lens whose convex face is oriented toward the object side; a jointed lens component CL1 which is formed by jointing a second lens L2 having positive refractive power and a third lens L3 having negative refractive power, and has positive refractive power as a whole; a fourth lens L4 having negative refractive power; a fifth lens L5 having positive refractive power; and a sixth lens L6 having positive refractive power. When an air interval on an axis between the first lens L1 and the second lens L2 is d2, and the focal distance of the first lens L1 on a d-line is f1, the wide angle lens satisfies the following expression: 0.01
