Abstract

The invention discloses a shooting lens and a camera device assembled with the shooting lens. The shooting lens comprises a first lens, a second lens, a third lens and multiple subsequent lenses; the first lens, the second lens, the third lens and the multiple subsequent lenses are arranged from the object side to the image side successively along the optical axis, and form a total effective focal length f; and the shooting lens is characterized in that a combined focal length f12 of the first and second lenses and a focal length f3 of the third lens satisfy that -0.7<f12/f3<0.

Description

technical field [0001] The present application relates to a camera lens and a camera device equipped with the camera lens. Background technique [0002] In recent years, with the improvement of semiconductor manufacturing technology, the pixel size of the photosensitive element has been continuously reduced. Correspondingly, the camera lens mounted on electronic products such as mobile phones and digital cameras has gradually developed towards the field of miniaturization and high pixel. [0003] Usually, in order to meet the requirements of high pixels, conventional camera lenses usually adopt a large-aperture configuration, resulting in a relatively long lens size, which makes it difficult to match high-pixel photosensitive chips. At the same time, in order to meet the high imaging quality, there is a certain limitation on increasing the field of view, which is usually overcome by increasing the number of lenses, but this cannot meet the requirements of miniaturization and...
