Patent ID: 8896937

Claim:
An image capturing lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface in a paraxial region thereof and a convex image-side surface in a paraxial region thereof; a second lens element with negative refractive power having a concave object-side surface in a paraxial region thereof and a convex image-side surface in a paraxial region thereof; a third lens element with positive refractive power having a concave object-side surface in a paraxial region thereof and a convex image-side surface in a paraxial region thereof; and a fourth lens element with refractive power having a concave image-side surface in a paraxial region thereof, wherein an object-side surface and the image-side surface of the fourth lens element are aspheric, and the image-side surface of the fourth lens element has at least one convex shape in an off-axis region thereof; wherein the image capturing lens assembly has a total of four lens elements with refractive power, a curvature radius of the image-side surface of the first lens element is R2, a curvature radius of the object-side surface of the second lens element is R3, an axial distance between the first lens element and the second lens element is T12, an axial distance between the second lens element and the third lens element is T23, an axial distance between the third lens element and the fourth lens element is T34, and the following conditions are satisfied: 1.9<R2/R3; and 2.1<T12/(T23+T24)<3.3.
