In an optical zoom tracking apparatus and method, and a computer-readable recording medium for performing the optical zoom tracking, the optical zoom tracking apparatus commands a focus lens to move according to a continuous zooming operation, such that a clear image can be maintained while the image is continuously zoomed in or out, resulting in the effective use of limited power if an optical zoom function of a digital camera or mobile phone is executed. The optical zoom tracking apparatus includes: a zoom lens, a focus lens interoperable with the zoom lens, a zoom-lens drive moving the zoom lens, a focus-lens drive moving the focus lens, and a focus-lens controller for determining a moving distance of the focus lens according to a moving distance of the zoom lens, and transmitting a control signal corresponding to the moving distance of the focus lens to the focus-lens drive.
