| 摘要 |
The present invention relates to a composite lens unit of an external optical system including a plurality of lens blocks and a moving unit moving while being coupled to the plurality of lens blocks, wherein the moving unit includes a blank area as the lens block moves for changing the mutual arrangement and a guide unit which guides the movement of the lens block. The composite lens of the external optical system makes an aberration correction condition good according to an F value of CCD or CMOS of a camera by using a refractive index of an optical lens, adjusts a view angle, and functions as wide angle, macro, fisheye, and telephoto lenses. |
