Problems solved by technology

[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, and it will be 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 light weight
[0004] Existing lenses are usually configured with the first positive lens and the second negative lens, as shown in the patent document with application number CN201420702086.8, this configuration makes the lens have a larger optical power on the light incident side, It often leads to a high sensitivity of the second negative lens system, which is not conducive to processing

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...
