Imaging lens and imaging apparatus
An imaging lens is provided and includes: in order from the object side, a negative first lens, a negative second lens, a positive third lens, a stop, and a positive fourth lens. In the lens, each of the second lens, the third lens, and the fourth lens has at least one aspheric surface, and an Abbe number of a material of the third lens at the d-line is 35 or less. In addition, the imaging lens satisfies the following Conditional Expression (1): −0.2<( R 3 +R 4)/( R 3 −R 4)<0.2 (1) where R 3 is a paraxial radius of curvature of the object side surface of the second lens, and R 4 is a paraxial radius of curvature of the image side surface of the second lens.
1. An imaging lens comprising: in order from an object side thereof,
a negative first lens;
a negative second lens;
a positive third lens;
a stop; and
a positive fourth lens,
wherein
the third lens is formed as a positive meniscus lens being convex toward the object side in a paraxial region, and
the fourth lens is formed as a positive meniscus lens being convex toward an image side in the paraxial region.
2. The imaging lens according to claim 1 ,
the first lens is formed as a negative meniscus lens being convex toward the object side in the paraxial region, and
the second lens is a bi-concave lens.
