摘要： This invention provides an optical image capturing lens system comprising: a negative first lens element having a convex object-side surface and a concave image-side surface at the paraxial region; a positive second lens element; a negative third lens element; a positive fourth lens element having a convex image-side surface at the paraxial region; and a negative plastic fifth lens element having a convex object-side surface at the paraxial region as well as a concave at the paraxial region and convex at the peripheral region image-side surface, at least one of the object-side and image-side surfaces being aspheric. The optical image capturing lens system of the present invention effectively increases the angle of view to a proper range and suppresses the distortion. In addition, the present invention has a tighter arrangement of the lens elements and a smaller back focal length, and therefore is more appropriate for the compact device.
