Abstract
A six-piece optical image capturing system is disclosed. In order from an object side to an image side, the optical lens along the optical axis includes a first lens with refractive power; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; a fifth lens with refractive power, and a sixth lens with refractive power. At least one of the image-side surface and object-side surface of each of the six lens elements is aspheric. The optical lens of the optical image capturing system can increase aperture value and improve the imagining quality for use in compact cameras.
