摘要： This disclosure provides an optical image capturing lens system comprising: a positive first lens element having a convex object-side surface, a negative second lens element, a positive third lens element having a convex image-side surface, a fourth lens element having a concave object-side surface and a convex image-side surface; and a positive fifth lens element having a convex object-side surface at a paraxial region thereof, both of the object-side and image-side surfaces being aspheric, and at least one inflection point is positioned on at least one of the object-side and image-side surfaces thereof. When particular relations are satisfied, the angle at which light projects onto the image plane can be efficiently controlled for increasing the relative illumination and preventing the occurrence of vignetting.
