Abstract

The invention discloses a photographing lens assembly, including a total of eight lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element and an eighth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. The eighth lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof. At least one lens element of the photographing lens assembly has at least one lens surface having at least one inflection point. When specific conditions are met, the photographing lens assembly can meet the requirements of miniaturization and high imaging quality at the same time. The invention further discloses an image capturing unit with the photographing lens assembly and an electronic device with the image capturing unit.

Description

technical field [0001] The invention relates to a camera lens group, an image pickup device and an electronic device, in particular to a camera lens group and an image pickup device suitable for the electronic device. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel size can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. [0003] With the rapid development of science and technology, the application range of electronic devices equipped with optical lenses is wider, and the requirements for optical lenses are also more diverse. Since the conventional optical lens is not easy to achieve a balance among requirements such as imaging quality, sensitivity, aperture size, volume, or viewing angle, the present invention provides an optical lens to meet the requirements.
