A wide angle lens whose field angle exceeds 180 degrees and whose F-number is less than 2.8, comprising: a front group, a diaphragm, and a rear group, which are arranged in the stated order from an object side toward an image side, wherein the front group consists of a first lens that is a negative meniscus lens whose convex surface is facing the object side, a second lens that is a negative lens, and a third lens that is a positive lens, which are arranged in the stated order from the object side toward the image side, the rear group consists of a fourth lens that is a positive lens, a fifth lens that is a negative lens, and a sixth lens that is a positive lens, which are arranged in the stated order from a diaphragm side toward the image side, the third lens in the front group is made of a material having an Abbe number of vdL3 that satisfies a condition of vdL3<21, and the fifth lens in the rear group is made of a material having an Abbe number of vdL5 that satisfies a condition of vdL5<21, characterised in that the first to sixth lenses form an imaging system including a total of six separate lenses, the second lens is a negative meniscus lens whose convex surface is facing the object, the third lens is a double-convex lens, the fourth lens is a double-convex lens, in which the surface having the larger curvature is facing the image, the fifth lens is a double-concave lens, the sixth lens is a double-convex lens, both surfaces of the second lens, both surfaces of the fourth lens, and both surfaces of the sixth lens are aspheric, and the first lens is a glass lens; and the second lens, the fourth lens, and the sixth lens are resin lenses. a front group, a diaphragm, and a rear group, which are arranged in the stated order from an object side toward an image side, wherein the front group consists of a first lens that is a negative meniscus lens whose convex surface is facing the object side, a second lens that is a negative lens, and a third lens that is a positive lens, which are arranged in the stated order from the object side toward the image side, the rear group consists of a fourth lens that is a positive lens, a fifth lens that is a negative lens, and a sixth lens that is a positive lens, which are arranged in the stated order from a diaphragm side toward the image side, the third lens in the front group is made of a material having an Abbe number of vdL3 that satisfies a condition of vdL3<21, and the fifth lens in the rear group is made of a material having an Abbe number of vdL5 that satisfies a condition of vdL5<21, characterised in that the first to sixth lenses form an imaging system including a total of six separate lenses, the second lens is a negative meniscus lens whose convex surface is facing the object, the third lens is a double-convex lens, the fourth lens is a double-convex lens, in which the surface having the larger curvature is facing the image, the fifth lens is a double-concave lens, the sixth lens is a double-convex lens, both surfaces of the second lens, both surfaces of the fourth lens, and both surfaces of the sixth lens are aspheric, and the first lens is a glass lens; and the second lens, the fourth lens, and the sixth lens are resin lenses.
