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