Abstract

A wide-angle lens assembly includes a first, a second, a third, a fourth, a fifth, a sixth, a seventh, and an eighth lenses, all of which are orderly arranged from an object side to an image side along an optical axis. The first, fourth, fifth, seventh, and eighth lenses are with refractive power. The second, third, and sixth lenses are with positive refractive power. The wide-angle lens assembly satisfies at least one of the following conditions: 0.8≤f/D22≤3; 0.025 degrees≤1/α≤0.3 degrees; 0.03 degrees≤1/β≤0.35 degrees; 0.5≤α/β≤30; wherein f is an effective focal length of the wide-angle lens assembly, D22 is an effective optical diameter of an image side surface of the second lens, α is a maximum tangent angle of a first cemented surface, and β is a maximum tangent angle of a second cemented surface.
