Optical image capturing lens system

An optical image capturing lens system comprising five lens elements, the five 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 and a fifth lens element;
• wherein the first lens element has positive refractive power, the second lens element has an object-side surface being convex in a paraxial region thereof, the fifth lens element has positive refractive power and at least one inflection point formed on at least one of an object-side surface and an image-side surface thereof;
• an aperture stop is disposed on the object side of the second lens element;
• wherein an axial distance between the third lens element and the fourth lens element is T34, which is larger than a central thickness of the third lens element;
• an axial distance between the fourth lens element and the fifth lens element is T45, a focal length of the optical image capturing lens system is f, a focal length of the fifth lens element is f5, and they satisfy the following relations:
• 0.55<f/f5<2.0;
• and
• 0<T45/T34<0.35.
