An optical lens assembly for image pickup, sequentially arranged from an object side to an image side along the optical axis, comprising: the first lens element with negative refractive power has a convex object-side surface and a concave image-side surface; the second lens element with positive refractive power has bi-convex surfaces; and the third lens element with negative refractive power, made of plastic, and which has a convex object-side surface and a concave image-side surface with at least one thereof is aspheric. By such arrangements, the optical lens assembly for image pickup satisfies conditions related to shorten the total length and to reduce the sensitivity for use in compact cameras and mobile phones with camera functionalities. |
