<p>A compact imaging lens includes, in order from the object side, a first lens (G1) having a convex surface on the object side and having a positive power; a second lens (G2) having a concave surface on the object side and having a negative power; a third lens (G3) having a positive power; and a fourth lens (G4) having a convex surface on the object side near the paraxial axis having a negative power and a meniscus shape. The imaging lens further satisfies a set of inequalities.</p> |
