Imaging lens and camera
By optimizing the focal length ratio and light height ratio of the lens group, and combining the design of positive lenses, negative lenses, and compound lenses, and using double aspherical lenses, the balance between image quality and size of camera lenses was solved, achieving miniaturization and high-quality imaging.

Abstract
The invention provides an imaging lens and a camera. The imaging lens comprises a first lens group, a second lens group and a third lens group which are sequentially arranged from an object side to an image side, the focal length of the first lens group is a first focal length; the focal length of the second lens group is a second focal length; the focal length of the whole optical system is a third focal length; under the condition that the length of the imaging lens along the first direction is determined, the ratio of the first focal length to the third focal length is 1.259-3.793; the ratio of the second focal length to the third focal length is 0.88-1.31; the first direction is the propagation direction of light in the imaging lens. The imaging quality of the imaging lens can be ensured under the condition that the lens body of the imaging lens is determined, so that the imaging quality and the size of the imaging lens are well balanced, and camera miniaturization is facilitated.
