Abstract

An imaging lens is substantially constituted by six lenses, including: a negative first lens having a concave surface toward the object side; a positive second lens; a negative third lens; a positive fourth lens of a meniscus shape with a concave surface toward the object side; a fifth lens; and a sixth lens having a concave surface toward the image side, the surface toward the image side thereof being an aspherical shape having at least one inflection point thereon, provided in this order from the object side. The imaging lens satisfies a predetermined conditional formula.

First claim

What is claimed is:

1. An imaging lens substantially consisting of six lenses, including:
a first lens having a negative refractive power and a concave surface toward the object side;
a second lens having a positive refractive power;
a third lens having a negative refractive power;
a fourth lens having a positive refractive power and is of a meniscus shape with a concave surface toward the object side;
a fifth lens; and
a sixth lens having a concave surface toward the im…
