Yes, sorry. All the action shots were at the lower ISO's. Where they played there was enough light.
What I tried to show you though is the quality of the higher ISO shots (action or not) and the crop-ability of the D800 is the reason I bought that camera and sold all my Canon gear.
The best thing is maybe you can either borrow/rent one or if there is a fellow photog that lives in your area that has one, you can give it a try and see as only you can say if you will be happy with it. I know I am.
