An imaging lens, an optical apparatus equipped therewith, and a method for manufacturing the imaging lens are provided. The imaging lens includes a front lens group having negative refractive power disposed to the most object side and a rear lens group having negative refractive power, disposed to an image side of the front lens group and moving at least a portion thereof in a direction including a component substantially perpendicular to an optical axis. The rear lens group includes G3a having negative refractive power, G3b having negative refractive power, and G3c having positive refractive power. G3b is disposed between G3a and G3c. G3b side lens surface of G3a is a concave surface facing G3b. G3b is a negative meniscus lens shape having a concave surface facing G3a. At least one lens surface among optical surfaces of G3a, G3b and G3c is an aspherical surface.
An imaging lens comprising:
A method for manufacturing an imaging lens including a front lens group having negative refractive power and a rear lens group having negative refractive power, the method comprising steps of:
