Telephoto lens and mobile terminal

Abstract

The disclosure provides a telephoto lens and a mobile terminal, form an object side to an imaging surface, sequentially includes: a first lens having a positive refractive power, a second lens having a refractive power, a third lens having a negative refractive power, a flat glass and a filter. An object side surface of the first lens is a convex surface, an image side surface of the third lens is s concave surface. The mobile terminal includes the telephoto lens, an image sensor, a processor and a memory. The image sensor are coupled to the telephoto lens, the two are cooperated to capture images. The processor is configured to process the captured images, and the memory is configured to store the captured images. The telephoto lens and the mobile terminal provided in the disclosure can achieve a higher zoom ratio than the conventional telephoto lens, and better satisfy the requirements of miniaturization and high-definition imaging of electronic products.
