Problems solved by technology

However, as the F number gradually decreases, especially when the F number is in the range of 1.2-1.5, the first few lenses in the camera lens group will become very large and the sensitivity will be very high, resulting in the inability of conventional processing and assembly capabilities. Meet the mass production requirements in actual production

Abstract

The invention discloses a camera lens group, which sequentially comprises a first lens with focal power, a second lens with positive focal power, a third lens with negative focal power, a fourth lenswith positive focal power, a fifth lens with focal power and a sixth lens with focal power from an object side to an image side along an optical axis. The object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; the object side surface of the second lens is a convex surface, and the image side surface of the second lens is a concave surface; the object side surface of the third lens is a concave surface, and the image side surface of the third lens is a concave surface; the object side surface of the fourth lens is a convex surface, and the image side surface of the fourth lens is a concave surface; and the object side surface of the sixth lens is a convex surface, and the image side surface of the sixth lens is a concavesurface. The F number Fno of the camera lens group meets the condition that Fno is less than or equal to 1.45.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to a camera lens group. Background technique [0002] At present, the market for portable electronic products such as mobile phones has higher and higher requirements for camera quality. Basically, every mobile phone will be equipped with at least one large-aperture camera. The larger the aperture of the camera, the more light passing through the camera per unit time, and the higher the clarity of the image. [0003] Generally, the larger the aperture of a camera, the smaller its F-number. However, as the F number gradually decreases, especially when the F number is in the range of 1.2-1.5, the first few lenses in the camera lens group will become very large and the sensitivity will be very high, resulting in the inability of conventional processing and assembly capabilities. Meet the mass production requirements in actual production. Contents of the invention [0004...
