Nhat V. Meyer's blog on SportsShooter discusses his Olympic experience and plugs the 200-400. http://www.sportsshooter.com/news/2046 'For all you gear-heads this is what I brought with me. And I will not be the first to proclaim this, but the Nikon 200-400 f4 is the perfect lens for covering the Olympics. That lens was awesome! Most of the time when we are covering events we can move around. The files are so nice that ISO is irrelevant, I often shot at 2500 an the files looked sweet and tack sharp with that 200-400. Love that lens! During the Olympics most of the time you pick a spot and that's where you sat for the duration. The 200-400 f4 gave me latitude to get images I would have been unable to get with a fixed 400 or a fixed 300.' Pretty good endorsement for those who have the cheddar for it.
