A wide-angle lens assembly includes a first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, and tenth lenses. The first and second lenses are meniscus lenses with negative refractive power. The third and ninth lenses are with negative refractive power. The fourth lens is with refractive power and includes a concave surface facing an object side. The fifth, sixth, and eighth lenses are with positive refractive power. The seventh lens is with refractive power and includes a concave surface facing the object side. The tenth lens is with refractive power and includes a concave surface facing an image side. The wide-angle lens assembly satisfies: 6<f/f<8.5; wherein fis an effective focal length in mm of the fifth lens and f is an effective focal length in mm of the wide-angle lens assembly.
