Abstract
The application discloses a camera lens group. The lens group comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens in sequence from an object side to an image side alongan optical axis, wherein the first lens has a positive focus; the object side of the first lens is a convex side; the image side of the first lens is a concave side; the second lens has a negative focus; object side of the second lens is a convex side; the image side of the second lens is a concave side; the third lens has a positive focus; the fourth lens has a positive focus; the fifth lens hasa negative focus; the object side of the fifth lens is a convex side; the image side of the fifth lens is a concave side; and the wavelength lambdan corresponding to 50 percent of the transmission rate of the camera lens group satisfies that (lambdan-700) (lambdan-800) is less than or equal to 0.
