Abstract
An imaging lens assembly includes first, second, third and fourth optical lens elements that are arranged sequentially from an object side to an image side along an optical axis. The first optical lens element and at least one of the second, third and fourth optical lens elements have positive refractive powers near the optical axis. At least one of object-side and image-side surfaces of at least one of the second to fourth optical lens elements is aspheric. The imaging lens assembly satisfies the following optical conditions: 0.7≦|f/f1|≦1.0, and HFOV≧35 deg, in which, f and f1 represent focal lengths of the imaging lens assembly and the first optical lens element, respectively, and HFOV stands for half field-of-view of the imaging lens assembly.
