Abstract

The invention provides a photographing optical lens assembly, an imaging apparatus and an electronic device. The photographing optical lens assembly includes eight lens elements, which are, in order from an object side to an image side along an optical path, 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. Each of the eight lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The first lens element has positive refractive power. The object-side surface of the fifth lens element is concave in a paraxial region thereof. The image-side surface of the sixth lens element is concave in a paraxial region thereof. The object-side surface of the seventh lens element is convex in a paraxial region thereof. The image-side surface of the eighth lens element is concave in a paraxial region thereof. When a specific condition is satisfied, the total length of the optical lens group for photographing can be shortened and a configuration of a large imaging surface can be provided.

Description

technical field

[0001] The present invention relates to an optical lens group for photography and an image-taking device, and in particular to a miniaturized optical lens group for photography and an image-taking device applied to electronic devices. Background technique

[0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixels can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. 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. Because the optical lenses in the past are not easy to meet the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, etc. Therefore, the present invention provides an optical lens to meet the requirements.
