Document Type and Number:
WIPO Patent Application WO/2018/103250
Kind Code:
A1
Abstract:
A camera lens, comprising, along an optical axis and sequentially from an object side to an image side, a first lens (L1), multiple successive lenses, and a photosensitive element disposed on an imaging plane. The first lens (L1) has a negative focusing power, and an object-side surface (S1) being a concave surface. The relationship between an on-axis distance TTL of the object-side surface (S1) of the first lens to the imaging plane and a half of a diagonal line length ImgH of an effective pixel region of the photosensitive element meets the following formula: 1.5 < TTL/ImgH < 1.7.
