The object-side surface of the first lens element has a convex portion in a vicinity of a periphery of the first lens element. The second lens element has negative refractive power. The object-side surface of the second lens element has a convex portion in a vicinity of a periphery of the second lens element. The image-side surface of the fifth lens element has a concave portion in a vicinity of the optical axis. The image-side surface of the sixth lens element has a concave portion in a vicinity of the optical axis.
