An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. At least one lens among the first to the fifth lenses has positive refractive force. The fifth lens can have negative refractive force, wherein both surfaces thereof are aspheric, and at least one surface thereof has an inflection point. The lenses in the optical image capturing system which have refractive power include the first to the fifth lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

Optical image capturing system

An optical image capturing system with four lenses is provided. In order from an object side to an image side, the optical image capturing system includes a first lens, a second lens, a third lens and a fourth lens. The first lens has positive refractive power and the object side thereof may be a convex surface. The second lens and the third lens have refractive power and the object side and the image side thereof may be all aspheric. The fourth lens has negative power and the image side thereof may be a concave surface. The object side and the image side of the fourth lens are aspheric and at least one surface thereof has one inflection point. When meeting some certain conditions, the optical image capturing system may have outstanding light-gathering ability and an adjustment ability about the optical path in order to elevate the image quality.
