Abstract
An image capturing lens assembly includes, 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 positive refractive power, a third lens element with refractive power, a fourth lens element with refractive power, a fifth lens element with refractive power having a convex image-side surface, and a sixth lens element with refractive power having a concave image-side surface. An object-side surface and the image-side surface of the sixth lens element are aspheric, and the sixth lens element has at least one inflection point formed on the image-side surface thereof.
