Abstract:
1. An image pick-up optical lens assembly, sequentially arranged from an object side to an image side along an optical axis, comprising: a first lens element with a positive refractive power, having a convex object-side surface; a second lens element with a negative refractive power; a third lens element with a positive refractive power; a fourth lens element with a positive refractive power, being a meniscus lens element, and at least one of the object-side and image-side surfaces being aspheric; a fifth lens element with a positive refractive power, having a convex object-side surface and a concave image-side surface, and at least one of the object-side and image-side surfaces being aspheric, and the image-side surface of the fifth lens element having at least one inflection point; wherein, f is the focal length of the image pick-up optical lens assembly, f
