Hi Steve, These are simply fantastic! Can you say how you set focus? You've obviously 'nailed' it! I assume AF-S but what were the other focus settings (e.g. area mode?, 3D-tracking?, auto area AF?, viewfinder view or LV?, etc.). Did you lock forces with the AF button or with the shutter release button?
Sorry for all the questions but you've achieved some great images and I'd love to learn just 'how'!
