Claim 0:
1. An optical image capturing lens assembly comprising six lens elements, the six lens elements being, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element, each of the six lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side;
wherein the first lens element has negative refractive power, the image-side surface of the first lens element is concave in a paraxial region thereof, the object-side surface of the second lens element is convex in a paraxial region thereof, the object-side surface of the fourth lens element is concave in a paraxial region thereof, the object-side surface of the fifth lens element is convex in a paraxial region thereof, at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric with at least one critical point in an off-axis region thereof, the object-side surface of the sixth lens element is convex in a paraxial region thereof;
wherein an axial distance between the third lens element and the fourth lens element is T34, an axial distance between the fourth lens element and the fifth lens element is T45, an axial distance between the fifth lens element and the sixth lens element is T56, a curvature radius of the object-side surface of the first lens element is R1, a curvature radius of the image-side surface of the third lens element is R6, and the following conditions are satisfied:

0.55<T56/(T34+T45)<32; and

0.60<R1/R6<19.
