Abstract:
Arranging a negative first lens, a positive second lens, a negative third lens, a positive fourth lens, and a positive fifth lens from the object side, in which the image side surface of the fifth lens has an aspherical shape with one or more inflection points and a concave shape toward the image side in a paraxial region, and, when the overall optical length, focal length of the entire lens system, focal length of the first lens, distance between image side surface of the second lens and object side surface of the third lens, refractive index of the second lens, and refractive index of the third lens are taken as TL, f, f1, Dg2-3, N2, and N3 respectively, the image capturing lens is configured to simultaneously satisfy conditional expressions (1a): 1.0≦TL/f≦1.8, (2a): 0.09
