Abstract
A wide-angle lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens is with negative refractive power and includes a convex surface facing an object side and a concave surface facing an image side. The second lens is with positive refractive power. The third lens is with positive refractive power and includes a convex surface facing the object side. The fourth lens is with negative refractive power. The fifth lens is with positive refractive power and includes a convex surface facing the image side. The sixth lens is with negative refractive power. The wide-angle lens assembly satisfies: −1.5<f/f≤−0.77, wherein fis an effective focal length of the first lens and fis an effective focal length of the fifth lens.
