摘要： There are provided an imaging lens, which is capable of promoting high definition and miniaturization of a small-size image pickup apparatus, and the small-size image pickup apparatus using the same. A aperture diaphragm S is arranged between a first lens L1 and a second lens L2 so that the first lens L1 is configured to be displaced into the orthogonal direction to the optical axis. Even when an error sensitivity of a lens is large, a stable high resolution can be secured by performing a lens alignment by displacing the first lens L1 into the orthogonal direction to the optical axis at the time of assembling, and thereby a high definition image can be obtained.

摘要： An image pickup lens system has a four-lens configuration which forms an image on a solid-state image pickup device. The image pickup lens system includes, from an object side, a positive first lens, an aperture stop, a positive second lens, a negative third lens whose concave surface is faced toward an image surface side, and a positive fourth lens in the order from an object side. A ratio of an axial lens thickness of the third lens to a focal length of the whole system is optimally set. Therefore, an exit pupil position can be kept far away from the image surface while the image pickup lens system has good optical performance and a compact size.
