Abstract
The present disclosure discloses a camera lens assembly includes, sequentially along an optical axis 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 first lens has a positive refractive power. At least one of the second lens, the third lens, or the fourth lens has a positive refractive power or a negative refractive power. The fifth lens has a positive refractive power, and an image-side surface of the fifth lens is a convex surface. The sixth lens has a negative refractive power. The seventh lens has a negative refractive power, and an object-side surface of the seventh lens is a convex surface. An effective focal length f1 of the first lens and an effective focal length f5 of the fifth lens satisfy: 1.5<f1/f5<3.5.
