So we have seen that the Nikon 800mm f5.6 lens was announced, but the MTF's are quite impressive and the new lens uses flourite glass in it as well. Also, the lens comes with a 1.25 TC as a standard accessory. However at US$18,000 in the States and at 4.6kg, it will not be for the feint hearted!! Knowing how Nikon Australia's "wisdom" works, I would say that it will be in the order of AU$20,000 for anyone that mabe interested here in Oz.
