Title:
CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2016/109956
Kind Code:
A1
Abstract:
A camera lens comprising sequentially from an object side to an image side: a first lens (E1) having a positive optical power and the object-side surface (S1) being a convex surface; a second lens (E2) having a negative optical power; a third lens (E3) having a negative optical power and the object-side surface (S5) being a concave surface; a fourth lens (E4) having a positive optical power; a fifth lens (E5) having a positive optical power and the image-side surface (S10) being a convex surface; and a sixth lens (E6) having a negative optical power and the image-side surface (S12) being a concave surface. The camera lens satisfies the relationships of: 0 < f/f4 <0.8 and 0 < T12/T23 < 0.14, where f is the effective focal length of the camera lens, f4 is the focal length of the fourth lens (E4), T12 is the axis pitch between the first lens (E1) and the second lens (E2), and T23 is the axis pitch between the second lens (E2) and the third lens (E3). Thus acquired is the compact camera lens that provides high image quality, is compact, and has a large aperture.
