Abstract:
1. An image capturing lens system, in order from an object side to an image side comprising: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power having a concave image-side surface; a plastic third lens element with refractive power having a concave object-side surface and a convex image-side surface, both the object-side and image-side surfaces thereof being aspheric; and a plastic fourth lens element with negative refractive power having a concave image-side surface, both the object-side and image-side surfaces thereof being aspheric, and at least one inflection point is formed on at least one of the object-side and image-side surfaces thereof, wherein a total number of lens elements with refractive power of the image capturing lens system is four and all the four lens elements with refractive power are non-cemented lenses; wherein the image capturing lens system comprises a stop positioned between the first lens element and the second lens element; wherein an axial distance between the third lens element and the fourth lens element is T
