To obtain a photographic lens which has a ≥60° photographic view angle without degrading the optical performance.
This photographic lens 10 has six-group constitution of a 1st lens group 11 to a 6th lens group 16 having negative, positive, positive, negative, positive, and negative power values in this order from the object side, and a stop 17 is provided between the 3rd lens group 13 and 4th lens group 14. The 1st lens group 11 is composed of a biconcave lens and the 6th lens group 16 has an aspherical concave surface on the object side. The 3rd lens group 13 consists of a cemented lens of an object side biconvex lens and an image- plane side meniscus negative lens and the 4th lens group 14 is formed of a cemented lens of an object side biconcave lens and an image-plane side biconvex lens. The photographic lens 10 has a ≥60° photographic field angle.
