Abstract
First, second, third, and fourth lenses (in order from an object side) are arranged between the object and an image sensor where an image of the object is formed. The first lens may have a positive refractive power and both surfaces thereof may be convex. The second lens may have a negative refractive power and both surfaces thereof may be concave. The third lens may have a positive refractive power and have a meniscus shape that is convex toward the image sensor. The fourth lens may have a negative refractive power and at least one of an incident surface and an exit surface thereof may be an aspherical surface. A sagittal depth SAGof an incident surface of the second lens along an optical axis and a sagittal depth SAGof an exit surface of the second lens along the optical axis may satisfy Inequality|SAG1|>|SAG2|.
