Miniaturized high-pixel shooting optical system and lens applying same

Abstract

One embodiment of the invention discloses a miniaturized high-pixel shooting optical system. The system at least successively comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object surface to an image surface along an optical axis, wherein the third lens and the fourth lens are bonded to each other to form a gummed lens, and the fifth lens is a double-convex aspheric lens; and the caliber ratio of the optical system is f / 2.4, the optical system satisfies the following conditions: 1), -1.2<f / f1<-0.6; 2), 0.45<f / f2<0.95; 3), -0.7<f / f34<-0.35, and 0.7<f / f5<1.25. On the other hand, another embodiment of the invention also provides a lens. According to the embodiments of the invention, the lens has a super wide viewing angle; at the same time, the optical total length of the optical system or the lens is shortened, and miniaturization of the optical system or the lens is realized; and besides, the optical system and the lens have excellent performance of providing total-interface clear images with more than four million pixels.
