Abstract

The invention discloses a camera lens and an electronic device. The camera lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and an infrared filter sequentially from an object side to an image side, wherein the third lens has positive focal power, and the fourth lens has positive focal power. The camera lens satisfies the conditional formula: 0.2< / =IMH / TTL< / =0.7, the IMH is an image height, and the TTL is an on-axis distance between the object side surface of the first lens and the imaging surface of the camera lens. Through the above design, the camera lenscan meet the requirements of high resolution and ultra-thin type. As the infrared filter is arranged between the fifth lens and the imaging surface to filter visible light and light with other bandsand only the infrared light can pass and enter an image sensor, the camera lens can thus be used as an infrared camera lens, that is, the camera lens can perform imaging and obtain good image effectsin a dim environment and other special application scenarios.
