A photographic small size objective of the modified Gauss type which is well corrected for high grade imaging performance. The objective comprises, from front to rear, a first lens in a meniscus form of positive power with its convex curvature toward the front, a second lens in a similar form, a third lens in a meniscus form of negative power with its convex curvature toward the front, a fourth lens in a meniscus form of negative power with its convex curvature toward the rear, and a fifth lens of positive power with its rear surface having a strong refractive power.
