ABSTRACT:
A lens position adjusting method for flange back adjustment of an inner focus lens assembly, which is suitable for a video camera is disclosed. The method comprises the steps of: moving a variator near to a telephoto end or a wide end; detecting a focal position by moving a focus lens when the variator is moved near to the telephoto end or the wide end; computing a difference in position between the variator and the telephoto end or the wide end, based on a moving distance of the focus lens to the focal position; and determining the position of the telephoto end or the wide end.
