PROBLEM TO BE SOLVED: To provide a photographic lens which is compact and lightweight, and has excellent imaging performance.SOLUTION: A photographic lens ML includes, in order from an object side along an optical axis, a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, and a third lens group G3 having positive refractive power, and is configured so that the second lens group G2 moves along the optical axis, when focusing from the infinity object to the finite distance object. The third lens group G3 includes, in order from the object side along the optical axis, a front group G3a having positive refractive power, and a rear group G3b having negative refractive power through the longest air interval in the third lens group G3 with respect to the front group G3a, and is configured so as to satisfy predetermined conditional expressions of the focal lengths of each of the lens groups. |
