The EXIF shows a Nikon D3 camera, with some lens at 70mm, f/2.8, and ISO 6400. We'll have to wait for the OP's comments on lens, but I'd guess at the 70-200/2.8VR since he'd want the ability to zoom in and get some "closeup" shots. At least, that's how I'd be thinking. It could also be the 24-70/2.8, though, or one of the older lenses in the lineup (28-70, 35-70, etc.)
I like the picture, but I have to say - it looks slightly oversharpened, and this brings out the noise in the image. It has the telltale pixelated lights from an image that may have been slightly over-sharpened.
