This invention provides an optical image capturing lens assembly comprising four lens elements, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a plastic third lens element with positive refractive power having a concave object-side surface and a convex image-side surface, the object-side and image-side surfaces thereof being aspheric; and a plastic fourth lens element with negative refractive power, an object-side surface and an image-side surface thereof being aspheric, at least one inflection point being formed on at least one of the object-side and image-side surfaces thereof. With the aforementioned arrangement, the total track length of the lens assembly can be effectively reduced, the sensitivity of the system can be attenuated and the image quality can be improved. |
