Abstract

The invention relates to a photographing optical lens assembly that includes seven 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 and a seventh lens element. The first lens element has negative refractive power. The third lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The fifth lens element has an object-side surface being concave in a paraxial region thereof. The sixth lens element has an object-side surface being convex in a paraxial region thereof. The seventh lens element has an image-side surface being concave in a paraxial region thereof and having at least one convex critical point in an off-axis region thereof. When specific conditions are met, the optical lens assembly for photographing can meet the requirements of miniaturization and large viewing angle at the same time. The invention further discloses an image capturing unit with the optical lens assemblyt for photographing and an electronic device with the image capturing unit.

Description

technical field [0001] The present invention relates to an optical lens group for photography, an image capturing device and an electronic device, in particular to an optical lens group for photography and an image capturing 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 pixels 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 t...
