摘要： An imaging lens substantially consists of six lenses of a negative first lens, a negative second lens, a positive third lens, a positive fourth lens, a negative fifth lens and a positive sixth lens in this order from an object side. An object-side surface of the second lens has a shape having negative refractive power at a center, and including a part having positive refractive power in an area between the center and an effective diameter edge, and having negative refractive power at the effective diameter edge (concave shape facing the object side), and the refractive power at the effective diameter edge being weaker than the refractive power at the center. Further, an object-side surface of the third lens is convex toward the object side. Further, a predetermined conditional formula about a combined focal length of the first lens, the second lens and the third lens is satisfied.

摘要： An imaging lens substantially consists of five lenses of a first lens having a meniscus shape with its convex surface facing an object side and negative refractive power, a second lens having negative refractive power, and the image-side surface of which has a convex shape facing an image side in the vicinity of an optical axis, a third lens having positive refractive power, a stop, a fourth lens having positive refractive power, and a fifth lens having negative refractive power. At least one of the surfaces of the first lens through the fifth lens is aspherical. A predetermined conditional formula about a distance on the optical axis from an object-side surface of the first lens to an image plane and a distance on the optical axis from the object-side surface of the first lens to the image-side surface of the second lens is satisfied.
