Title: IMAGE PICKUP LENS AND IMAGE PICKUP APPARATUS PROVIDED WITH IMAGE PICKUP LENS
Abstract:
[Problem] To provide an image pickup lens having a reduced total length and high resolution, and an image pickup apparatus that is provided with the image pickup lens. [Solution] In this image pickup lens, a length from a first lens (L1) surface on the object side to an image forming surface, said length being on an optical axis, is 10 mm or less. The image pickup lens is configured of six lenses sequentially disposed from the object side, said six lenses being: a first lens (L1), which has positive refractive power, and which has a convex surface facing the object side; a second lens (L2) having negative refractive power; a third lens (L3) having positive refractive power; a fourth lens (L4) having negative refractive power; a fifth lens (L5) having positive refractive power; and a sixth lens (L6) wherein the image-side surface is concave to the image side in the vicinity of the optical axis, and is convex to the image side at the periphery of the optical axis. The image pickup apparatus is provided with an aperture stop (St), which is disposed further toward the object side than the image-side surface of the third lens (L3).
