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 and having a convex object-side surface; a second lens element with refractive power; a third lens element with positive refractive power and having a convex image-side surface; and a fourth lens element with refractive power and having a convex object-side surface and a concave image-side surface, wherein the object-side surface and the image-side surface of the fourth lens element are aspheric, and the fourth lens element has at least one inflection point formed on at least one of the object-side surface and the image-side surface thereof; wherein a central thickness of the first lens element is CT1, a central thickness of the second lens element is CT2, a central thickness of the third lens element is CT3, a central thickness of the fourth lens element is CT4, 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, a curvature radius of the object-side surface of the second lens element is R3, and a curvature radius of the image-side surface of the second lens element is R4, the following relationships are satisfied: 0.2<( CT 1+ CT 2+ CT 4)/ CT 3<0.93; 0<( T 23+ T 34)/ T 12<1; and 0<( R 3+ R 4)/( R 3 −R 4)<5.
