Abstract:
An imaging lens and an imaging apparatus capable of acquiring a long-distance object image at high resolution and capable of acquiring a short-distance object image in a wide range while, as a whole, being configured small. In order to achieve the object, an imaging lens according to the present invention is an imaging lens consisting of n (n is a natural number equal to or larger than six) lenses including a first lens having negative refractive power and a second lens having positive refractive power in order from an object side and including an n-th lens having negative refractive power and an n−1-th lens having positive refractive power in order from an image side, the imaging lens satisfying a predetermined conditional expression.
