Patent attributes
This disclosure provides an imaging lens system, including, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a third lens element with refractive power; a fourth lens element with refractive power having an object-side surface and an image-side surface thereof being aspheric; a fifth lens element with refractive power having a convex object-side surface, the object-side surface and an image-side surface thereof being aspheric, and at least one of the object-side surface and the image-side surface being provided with at least one inflection point. The imaging lens system is further provided with a stop, and no lens element with refractive power is disposed between the stop and first lens element.
