One needs a camera that easily goes up to at least ISO 25,000 to 50,000 so that the shutter speed can be at least 1/250th sec at f/8.
As an aside, if you are choosing f/8 because that is needed to get adequate DOF in 35mm, you could be doing the same with about f/5 in "APS-C" formats, f/4 with 4/3" format, f/3 with Nikon's new 1" format, which in turn allows you to reduce the ISO speed needed by about one, two, or three stops respectively, to about 11,000 or 6,400 or 3,600 for those formats in place of 25,000 in 35mm format.
Bigger sensors only have a fundamental low-light/high shutter speed advantage when used with "big glass", meaning bigger aperture diameters than smaller formats offer, which means keeping to low aperture ratios.
