5th lens have positive light coke or negative power, and its thing side is concave surface, and image side surface is convex surface or plane；And

The synthesis focal length f12 of first lens and second lens and the 4th lens and the 5th lens synthesis Focal length f45 meets -1≤f12/f45≤0.

14. imaging lens, are sequentially included along optical axis by thing side to image side：First lens, the second lens, the 3rd lens, the 4th Lens and the 5th lens,

Characterized in that,

First lens have positive light coke, and its thing side is convex surface；

Second lens have negative power, and its thing side and image side surface are concave surface；

3rd lens have negative power；

4th lens have positive light coke or negative power；

5th lens have positive light coke or negative power, and its thing side is concave surface, and image side surface is convex surface or plane；And

The focal length f1 of first lens, the focal length f2 of second lens and the 5th lens focal length f5 meet 0≤f1* f2/f5≤6mm。
