Title:
CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2018/045607
Kind Code:
A1
Abstract:
A camera lens, comprising sequentially from the object side to the image side: a first lens (L1) having a negative optical power; a second lens (L2) having an optical power; a third lens (L3) having a positive optical power and a lateral surface being a concave surface; a fourth lens (L4) having an optical power; a fifth lens (L5) having an optical power; a sixth lens (L6) having an optical power; and a seventh lens (L7) having an optical power and the object-side surface and the image-side surface being non-spherical surfaces. The camera lens satisfies the conditional expression of: -2 < f1/f < -1.4, where f1 is the effective focal length of the first lens (L1), and f is the effective focal length of the camera lens. The present camera lens can effectively correct various high-order aberrations so as to reduce distortions, has a high relative illumination, increased resolution, and further compact size at the same time, and is applicable in different work environments.
