Abstract:
1. An optical image capturing lens system comprising, in order from an object side to an image side: a first lens element with positive refractive power having an object de surface being convex at a paraxial region; a second lens element with positive refractive power made of plastic material, and having an object-side surface being convex at a paraxial region and an image-side surface being concave at a paraxial region, wherein the object-side surface and the image-side surface of the second lens element are aspheric; and a third lens element with negative refractive power made of plastic material, and having an object-side surface being concave or planar at a paraxial region and an image-side surface being concave at a paraxial region and being convex at a peripheral region, wherein the object-side surface and the image-side surface of the third lens element are aspheric; wherein a curvature radius of the image-side surface of the second lens element is R4, a curvature radius of the object-side surface of the third lens element is R5, and the following relationship is satisfied:
