I have been planning on buying a D80 in the next couple months, but just realized that it has the rather slow flash sync speed of 1/200 of a second. Will this be a problem when shooting skateboarding and snowboarding? I was looking at the Nikon d70s because that has a sync speed of 1/500 of a second. Any major issues with that or things where it is not as good as the D80? How big could one print from the 6.1 megapixels of the d70s?
