Abstract

The invention provides a camera lens. The camera lens includes, in an order from an object side to an image side: a first lens with a negative refractive power, a second lens with a positive refractive power, a third lens with a positive refractive power, a fourth lens with a negative refractive power, a fifth lens with a positive refractive power, and a sixth lens with a negative refractive power. Further, the camera lens satisfies specific conditions for improving better performance.

Claims (40)

1. A camera lens, comprising, in an order from an object side to an image side: a first lens with a negative refractive power, a second lens with a positive refractive power, a third lens with a positive refractive power, a fourth lens with a negative refractive power, a fifth lens with a positive refractive power, and a sixth lens with a negative refractive power; wherein the camera lens further satisfies the following conditions (1)˜(3):
