The invention relates to an optical system, a camera module, an electronic device and an automobile. The optical system includes, in order from an object side to an image side, a first lens element with negative refractive power, a second lens with positive refractive power, a third lens with positive refractive power, a fourth lens with positive refractive power, and a fifth lens with negative refractive power. The object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface. The object side surface of the second lens is a convexsurface; the object side surface of the third lens is a concave surface, and the image side surface of the third lens is a convex surface; the object side surface and the image side surface of the fourth lens are convex surfaces; the object side surface of the fifth lens is a concave surface, and the image side surface of the fifth lens is a convex surface; the optical system further comprises adiaphragm arranged on the object side of the fourth lens. The system meets the following relationship: Imgh/f is greater than 1.5 and less than or equal to 3.5, Imgh is the diagonal length of the imaging surface of the optical system in the effective imaging area, and f is the effective focal length of the optical system. When the relation is met, miniaturization and wide-angle design of the system are facilitated, and meanwhile the system has the high pixel characteristic.

    本发明涉及一种光学系统、摄像模组、电子装置及汽车。光学系统由物侧至像侧依次包括:具有负屈折力的第一透镜;具有正屈折力的第二透镜、第三透镜及第四透镜,及具有负屈折力的第五透镜。第一透镜的物侧面为凸面,像侧面为凹面;第二透镜的物侧面为凸面;第三透镜的物侧面为凹面,像侧面为凸面;第四透镜的物侧面和像侧面均为凸面;第五透镜的物侧面为凹面,像侧面为凸面;光学系统还包括设于第四透镜物侧的光阑;且系统满足关系:1.5<Imgh/f≤3.5;Imgh为光学系统的成像面于有效成像区域的对角线长度,f为光学系统的有效焦距。满足上述关系时将有利于系统的小型化及广角化设计,同时有利于系统拥有高像素特性。
