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 having negative refractive power and having a convex object-side surface and a concave image-side surface; a second lens having negative refractive power and having a convex object-side surface and a concave image-side surface; a third lens with positive refractive power; a fourth lens with positive refractive power; a fifth lens with positive refractive power; a sixth lens having negative refractive powerand having a concave object-side surface and a convex image-side surface; and a middle diaphragm. The optical system meets the relation that f456/f is larger than 0 and smaller than 3, wherein f456 isthe combined focal length of the fourth lens, the fifth lens and the sixth lens, and f is the effective focal length of the optical system. When the above relation is satisfied, the miniaturization design of the system can be realized, and the imaging definition of the system can be improved.
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,第一透镜的物侧面为凸面,像侧面为凹面;具有负屈折力的第二透镜,第二透镜的物侧面为凸面,像侧面为凹面;具有正屈折力的第三透镜;具有正屈折力的第四透镜;具有正屈折力的第五透镜;具有负屈折力的第六透镜,第六透镜的物侧面为凹面,像侧面为凸面;光学系统还包括中置光阑,且光学系统满足关系:0<f456/f<3;其中,f456为第四透镜、第五透镜及第六透镜的组合焦距,f为光学系统的有效焦距。满足上述关系时,将有助于实现系统的小型化设计,同时还能提高系统的成像清晰度。
