The invention relates to an optical system, a camera module, electronic equipment and an automobile. The optical system includes: a first lens having negative refractive power; a second lens element with positive refractive power; a third lens element with positive refractive power and having an image-side surface being convex near the optical axis; a fourth lens element with refractive power and having a convex object-side surface near the optical axis; a fifth lens element with refractive power; and a sixth lens element with refractive power; the optical system satisfies the following relation: FOV/EPD is larger than 19.4 deg/mm and smaller than 24.3 deg/mm; wherein the FOV is the maximum field angle of the optical system, and the EPD is the entrance pupil diameter of the optical system. The optical system can obtain an image with a large visual field range, meanwhile, can obtain information of a large depth in the image and have a clear recognition capability for both a long shot and a close shot, and in addition, can obtain a high-definition image through sufficient brightness brought by the characteristic of a large aperture.

    本发明涉及一种光学系统、摄像模组、电子设备及汽车。光学系统,包括:具有负屈折力第一透镜;具有正屈折力的第二透镜;具有正屈折力的第三透镜,其像侧面于近光轴处为凸面;具有屈折力的第四透镜,其物侧面于近光轴处为凸面;具有屈折力的第五透镜;具有屈折力的第六透镜;且光学系统满足关系:19.4deg/mm<FOV/EPD<24.3deg/mm;FOV为光学系统的最大视场角,EPD为光学系统的入瞳直径。上述光学系统在获得较大视野范围的影像的同时,还能够获得影像中的较大深度的信息以针对远景及近景均拥有清晰的识别能力,另外还能通过大光圈特性所带来的充足亮度以获得高清晰成像。
