The invention relates to a lens system, an image capturing module, an electronic device and a driving device. The lens system includes, in order from an object side to an image side along an optical axis, a first lens element with negative refractive power having a concave image-side surface; a second lens element with positive refractive power; a third lens element with negative refractive powerhaving a concave object-side surface and a concave image-side surface; a fourth lens element with positive refractive power having a convex image-side surface; a fifth lens element with positive refractive power; and a diaphragm provided on the object side of the lens system or between the first lens and the fifth lens. The lens system has a wide viewing angle, a large depth-of-field range and high resolution capability when meeting a specific relationship, and also has the characteristic of miniaturization.
本申请涉及一种透镜系统、取像模组、电子装置及驾驶装置。透镜系统沿着光轴由物侧至像侧依序包括具有负屈折力的第一透镜,其像侧面为凹面;具有正屈折力的第二透镜;具有负屈折力的第三透镜,其物侧面为凹面,像侧面为凹面;具有正屈折力的第四透镜,其像侧面为凸面;具有正屈折力的第五透镜;以及光阑,设于透镜系统的物侧或者第一透镜和第五透镜之间。上述透镜系统在满足特定关系时,具备广视角、较大的景深范围以及高解像能力,同时还具有小型化的特点。
