It is a misconception to think that all lenses need to be multicoated. Nikon, Contax, Canon and Leica all coat lenses based on what their design team decides is best for each individual element. Some elements need one coat, some two or three, some more. Nikon calls it NIC (Nikon Integrated Coating) and Zeiss's T* coating is the same. It all depends on the formula for the lens. In fact, to put the same coating on each lens element is only going to degrade performance. ========== Eric Welch St. Joseph, MO http://www.ponyexpress.net/~ewelch He, who will not reason, is a bigot; he, who cannot, is a fool; and he, who dares not, is a slave.
