Wide angle imaging lens

A wide angle imaging lens comprising, in order from an object side:

• a first lens of a meniscus lens having a negative refractive power and having a convex surface on the object side;
• a second lens having a negative refractive power and having a concave surface on an image side, at least one of both surfaces of the second lens being aspheric;
• a third lens having a positive refractive power and having a convex surface on the object side, at least one of both surfaces of the third lens being aspheric;
• an aperture diaphragm;
• and
• a fourth lens having a positive refractive power and having a convex surface on the image side, at least one of both surfaces of the fourth lens being aspheric, wherein
• the first lens comprises a material having Abbe number at d line of 40 or more, the second lens comprises a material having Abbe number at d line of 50 or more,
• the third lens comprises a material having Abbe number at d line of 40 or less, the fourth lens comprises a material having Abbe number at d line of 50 or more, and
• the wide angle imaging lens satisfies Condition Equation (4):
• 0.10<f/D<0.22 (4)
• wherein f represents a focal length of the entire system of the wide angle imaging lens, and D represents a distance from a surface on the object side of the first lens to a surface on the image side of the fourth lens.
