Claim Text:
1. An five-piece lens assembly for capturing images, in order from an object side toward an image side along an optical axis comprising: a first lens element with positive refractive power having a convex image-side surface and a convex object-side surface adjacent to the optical axis, and at least one of the image-side surface and the object-side surface of the first lens element being aspheric; a second lens element with refractive power having a concave image-side surface adjacent to the optical axis, and at least one of the image-side surface and the object-side surface of the second lens element being aspheric; a third lens element with refractive power, an image-side surface and an object-side surface of the third lens element being aspheric, and both of the object-side surface and the image-side surface of the third lens element having inflection points; a fourth lens element with refractive power having a concave object-side surface and a convex image-side surface adjacent to the optical axis; and a fifth lens element with refractive power having a concave object-side surface and a convex image-side surface adjacent to the optical axis, the image-side surface and the object-side surface of the fifth lens element being aspheric, and the object-side surface of the fifth lens element having at least one inflection point and the image-side surface of the fifth lens element having at least two inflection points; wherein focal lengths from the first through fifth lens elements are f1, f2, f3, f4, and f5, respectively, a focal length of the five-piece lens assembly for capturing images is f, a distance between the image-side surface of the fourth lens element and the object-side surface of the fifth lens element on the optical axis is T45, and they are satisfied with following condition:
