Claim 0:
1. An optical imaging system comprising:
a first lens having positive refractive power, a convex object-side surface and a convex image-side surface;
a second lens having negative refractive power, a convex object-side surface in a paraxial region, and a concave image-side surface;
a third lens having negative refractive power, a convex object-side surface and a concave image-side surface;
a fourth lens having negative refractive power, a convex object-side surface and a concave image-side surface;
a fifth lens having negative refractive power; and
a sixth lens having positive refractive power, and a convex image-side surface in a paraxial region,
wherein the first to sixth lenses are sequentially disposed on an optical axis from an object side toward an image side,
wherein among the first to sixth lenses, the fourth lens has the largest absolute focal length value, and
wherein a field of view of the optical system including the first to sixth lenses is FOV and FOV≤44°.
