^^^Because the lens he used IS a fisheye lens and not an adapter....Prolly used something like 10.5mm lens to do that...An adapter leaves you with all that black around the pic...Also, any dslr should be fast enough....really depends more on the lens though...The lens that comes with the cam isnt gonna be fast enough....But, the lens you need to actually freeze a paintball could actually cost more than your camera lol
