Abstract
An optical lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, all of which are arranged in sequence from an object side to an image side along an optical axis. The first lens is with positive refractive power and includes a convex surface facing the object side. The second lens is with refractive power. The third lens is with refractive power. The fourth lens is a meniscus lens with refractive power. The fifth lens is with positive refractive power. The sixth lens is with positive refractive power. The optical lens assembly satisfies: −1.8≤f/f≤−1.3 wherein fis an effective focal length of the fourth lens and f is an effective focal length of the optical lens assembly.
