Problems solved by technology

However, with the continuous development of portable electronic products such as smartphones, higher requirements are put forward for imaging lenses, especially for situations such as insufficient light (such as rainy days, dusk, etc.), hand shake, etc., so the F number of 2.0 or above Can no longer meet higher-level imaging requirements

Abstract

The invention discloses a camera shooting lens assembly. The camera shooting lens assembly comprises a first lens with the positive focal power, a second lens with the positive focal power, a third lens with the positive focal power, a fourth lens, a fifth lens with the focal power, a sixth lens with the focal power and a seventh lens with the negative focal power, wherein the object side face of the first lens is a convex face, the object side face of the fifth lens is a concave face, the image side face of the fifth lens is a convex face, the image side face of the sixth lens is a concave face, the image side face of the seventh lens is a concave face, and the effective focal length f of the camera shooting lens assembly and the entrance pupil diameter EPD of the camera shooting lens assembly meets the equation that f / EPD<=1.60. The camera shooting lens assembly is applicable to portable electronic products, and is an optical system with the large aperture, good image quality and low sensitivity.

Description

technical field [0001] The invention relates to a camera lens group, in particular to a camera lens group composed of seven lenses. Background technique [0002] With the development of science and technology, the market's requirements for product-side imaging lenses are becoming more and more diverse. Portable electronic products tend to be more and more miniaturized, which limits the overall length of the lens, thus increasing the difficulty of lens design. In order to meet the requirement of miniaturization, the F-numbers of existing lenses are usually configured at or above 2.0, so as to reduce the size of the lens while having good optical performance. However, with the continuous development of portable electronic products such as smartphones, higher requirements are put forward for imaging lenses, especially for situations such as insufficient light (such as rainy days, dusk, etc.), hand shake, etc., so the F number of 2.0 or above It has been unable to meet the hig...
