Abstract: An optical lens system includes six lens elements from an object side to an image side, the six lens elements are, in order from the object side to the image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. Each of the six lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The image-side surface of the second lens element is concave in a paraxial region thereof. The third lens element has positive refractive power. The image-side surface of the fourth lens element is concave in a paraxial region thereof. The image-side surface of the sixth lens element includes at least one inflection point.
