Photographing lens and photographing apparatus

摘要

A photographing lens and a photographing apparatus including the photographing lens. The photographing lens includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens that are arranged sequentially from an object side. The first lens has a concave surface toward the object side and has a positive refractive power, and the second lens is formed with a meniscus shape having a concave surface toward an image side and has a negative refractive power.

1. A photographing lens, wherein:
the photographing lens is a camera lens, and comprises: exactly five lenses, consisting of a first lens, a second lens, a third lens, a fourth lens, and a fifth lens that are arranged sequentially from an object side to an image side, wherein the first lens has a concave surface toward the object side and has a positive refractive power, the second lens is formed with a meniscus shape having a concave surface toward the image side and has a negative refractive power, the third lens has a negative refractive power, the fourth lens has a positive refractive power, and the fifth lens has a negative refractive power, and wherein the first lens satisfies the inequality; 7.0<|R1/R2|<1200,where R1 denotes the radius of curvature of the object side surface of the first lens around the optical axsi, and R2 denotes the radius of curvature of the image side surface of the first lens around the optical axis.
