Nikkor 200-400/4 VR lens announced

For those of you with the muscles and the budget to afford it, Nikon has just announced a new 200-400/4 VR lens, equivalent to 300-600 for the digital models. The advantage would of course be the additional shutter speed at the upper end of the range, 1/500 vs 1/250 and the like. The lens has some additional innovative features of interest, including preset focusing positions, apparently done electronically.
