PURPOSE: To obtain a photographing lens whose entire length is relatively short, where chromatic aberration of magnification and distortion aberration are completely compensated and which is suitable for a film unit with a lens or a fixed focus camera.
CONSTITUTION: This photographing lens is constituted of a 1st meniscus shaped lens whose convex surface is faced to an object side and which has positive refractive power, a 2nd meniscus shaped lens whose concave surface is faced to the object side and which has the positive refractive power in order from the object side. When it is assumed that the focal length of the entire lens system is (f), the focal length of the 1st lens is f1, the radius of curvature of the object side surface of the 2nd lens is r3, and the radius of curvature of the image side surface thereof is r4, the photographing lens satisfying the following conditional expressions is obtained: 0.50<f/f1<0.90 and -8<(r4+r3)/(r4-r3)<-1.5.
