摘要： This invention provides an image lens system comprising: a first lens element with positive refractive power; a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, both the object-side and image-side surfaces thereof being aspheric and made of plastic; a third lens element with positive refractive power; and a fourth lens element with negative refractive power, and at least one inflection point is formed on at least one of the object-side and image-side surfaces thereof; wherein, the region of the image-side surface of the second lens element near the optical axis is concave, but the off-axis region thereof is convex. By such arrangement, not only the photosensitivity and total track length of the system can be reduced, but also better image quality can be obtained.
