An optical lens assembly includes a stop and, in order from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. The optical lens assembly has a half of a maximum field of view of the optical lens assembly a distance from an image-side surface of the seventh lens to an image plane on an optical axis, a radius of curvature of an object-side surface of the fourth lens, and a radius of curvature of an image-side surface of the fourth lens. An appropriate configuration of a high-quality lens module with the maximum field of view and an optical back focal length can be provided, to avoid interference of the structural appearance.

Optical lens assembly and photographing module

An optical lens assembly includes, in order from the object side to the image side: a stop, a first lens element, a second lens element, a third lens element, and an infrared bandpass filter. An entrance pupil diameter of the optical lens assembly is EPD, a half of a maximum field of view of the optical lens assembly is HFOV, and the following condition is satisfied: 0.59&#x3c;EPD/tan(HFOV)&#x3c;1.33.
