An imaging lens and imaging apparatus are disclosed. In one example, an imaging lens includes a first lens group having positive refractive power, a second lens group having a positive refractive power, and a third lens group having positive or negative refractive power, the first lens group being fixed with respect to an image plane, the second lens group traveling along an optical axis to the object side, and the third lens group being fixed with respect to the image plane. The first lens group may include two positive lenses and a negative lens. The second lens group may include a second a-lens component having negative refractive power and a second b-lens component having positive refractive power. The third lens group may include a third a-lens component having positive refractive power and a third b-lens component having negative refractive power.
