<p>A zoom lens focus adjustment apparatus is provided. The apparatus includes a focusing part, a variator, and a compensator. The focusing part is disposed in a front side and focuses on an object. The variator changes a zoom ratio using a lens of a variable refractive power that changes the refractive index of the lens using a voltage applied from the outside, thereby performing a zooming operation of a zoom lens. The compensator compensates for the position of an image plane using the change of the zoom ratio by the variator.</p> |
