        Supplementary lnstructions on Remounting of Cintar Lens
        Your Cintar Lens does not have a visible focusing scale, therefoh
        you cannot set your lens at the infiniry (m) position as described
         for the Telephoto or Vide Angle lens. Before installing your
         Cintar Lens you will have to refer to the rear of your lens. You
          will see two white dots. One of these dots is located on a movable
          ring, whereas the other dot is on a stationary ring. Your lens is
          focused at the infinity (00) position when the two white dots are
          lined up opposite eaih other.- If the white dots are not in line you
       may turn the movable ring in either direction until they are cor-
          rectly aligned.

depth of field

   The depth of field scale on top of your
    Lithagon lenses tells you how much of your
    pictuie is in sharp focus. Depth of field varies
    with distances and f-settings, but this scale
    always tells you what it is.
                    '       E*ample: \7ith your camera set
