Abstract: An image capturing lens system includes, 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 having an object-side surface and an image-side surface which are both aspheric; a fourth lens element with negative refractive power having an object-side surface and an image-side surface which are both aspheric; a fifth lens element having an object-side surface and an image-side surface which are both aspheric; and a sixth lens element having a concave object-side surface and a convex image-side surface which are both aspheric. With such arrangements, the convergent capability is mainly contributed from the object side of the lens assembly for higher portability of the lens system. Additionally, the peripheral image curve can be prevented while correcting the chromatic aberration and the peripheral image focus.
Abstract translation: 图像拍摄透镜系统从物体侧到像侧依次包括：具有凸面物侧的正屈光力的第一透镜元件; 具有负屈光力的第二透镜元件; 具有非球面的物体侧表面和图像侧表面的第三透镜元件; 具有负屈光力的第四透镜元件，具有物镜侧表面和图像侧表面都是非球面的; 具有非球面的物体侧表面和图像侧表面的第五透镜元件; 以及具有凹凸物侧表面和凸面像侧面的第六透镜元件都是非球面的。 通过这样的布置，会聚能力主要由透镜组件的物体侧贡献，以提高透镜系统的便携性。 此外，可以在校正色差和周边图像焦点的同时防止周边图像曲线。
