Abstract

The invention discloses an optical lens set for camera shooting and a camera shooting device of the optical lens set for camera shooting. The optical lens set for camera shooting sequentially comprises a prism, a first lens group, a second lens group, a third lens group and a fourth lens group along optical shaft arrangement. The prism is a full-reflecting lens. The first lens group has negative focal power and comprises at least one lens with the negative focal power. The second lens group has the positive focal power and comprises at least one lens with an aspheric optical face. The third lens group has positive focal power and comprises at least one lens with positive focal power and at least one lens with negative focal power. The fourth lens group has positive focal power and comprises at least one lens with an aspheric optical face. Therefore, the optical lens set for camera shooting and the camera shooting device of the optical lens set for camera shooting can also be applied to a thin lens module applied to camera shooting, apart from the good function of aberration correction.

Description

technical field [0001] The present invention relates to an optical lens group for imaging and its imaging device, in particular to an optical lens group for imaging and its imaging device composed of a prism and four groups of lenses, for application in a thin imaging system. Background technique [0002] On small electronic devices such as Digital Still Cameras, Mobile Phone Cameras, and Web Cameras, periscope-type optical lens groups for imaging are often installed, and most of them are zoom-type. It is used to take pictures of the subject, and the main trend of the development of the optical lens group for photography is towards thinner and lower cost, but at the same time it is also expected to achieve good aberration correction capabilities, high resolution, and high imaging High-quality camera optics. [0003] In the known optical lens group for imaging, an additional lens with a concave surface on the image side or a crescent lens with a convex surface on the object ...
