Abstract

The invention relates to a camera lens, which comprises a first lens (1), a diaphragm (S), a second lens (2), a third lens (3), a fourth lens (4), and a fifth lens (5) arranged in sequence along the optical axis from the object side to the image side, the first lens (1) and the fourth lens (4) are negative power lenses, the object-side surface of the second lens (2) is concave, the third lens (3)and the fifth lens (5) are positive power lenses; a relationship between the maximum effective radius DT21 of the side surface of the second lens (2) and the maximum effective radius DT31 of the sidesurface of the third lens (3) is satisfied: 0.45<DT21 / DT31<1.0. The camera lens of the present invention is a miniaturized lens, the size is small, and the camera lens has an extremely large field ofview angle and can achieve a good imaging effect.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a camera lens. Background technique [0002] With the continuous development of smartphone photography technology, camera modules have developed from single-camera, dual-camera to triple-camera, or even quadruple-camera. It has become a mainstream trend to equip at least one ultra-wide-angle lens. Therefore, the market demand for this type of lens is also increasing. However, although the camera lens of the existing smart phone has a large field of view, its volume is relatively large, which makes the thickness or volume of the smart phone larger after being loaded into the smart phone, and the smart phone becomes bulky, making the operation and portability difficult. Even more inconvenient. Contents of the invention [0003] An object of the present invention is to solve the above problems and provide a miniaturized camera lens with a super large viewing angle. [0004] In or...
