Abstract

The invention discloses a camera lens group. The camera lens group comprises a first lenswith focal power, a second lens with focal power, a third lens with positive focal power, a fourth lenswith focal power, a fifth lens with positive focal power and a sixth lens with negative focal power along the optical axis from the object side to the image side in sequence, whereinthe object side surface ofthe first lens is a concave surface, and the image side surface is a convex surface; the object side surface of the second lens is a convex surface, and the image side surface is a concave surface;the object side surface of the fifth lens is aconcave surface, and the image side surface is aconvex surface; object side surface of the sixth lens is aconvex surface, and the image side surface is aconcave surface. Ahalf of diagonal line length ImgH in the effective pixel region on the imaging surface of the camera lens group meets the condition that ImgH is larger than 4.60 mm.

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, with the rapid development of portable electronic products such as smart phones and tablet computers, users have higher and higher requirements on the camera function of portable electronic products. Users hope that the camera function of mobile phones can provide shooting effects similar to those achieved by professional camera equipment. [0003] In order to improve the shooting effect of mobile phones as much as possible, multi-camera lenses such as dual-camera and triple-camera came into being. At present, the more common multi-camera lenses are mostly wide-angle + telephoto combinations. The combination of wide-angle lenses and telephoto lenses can greatly improve the shooting effect of mobile phone lens modules. In particular, when the wide-angle lens can take into account the characteristics of wide...
