I took the shot with a 5D, 70-200 f/2.8:

Exposure: 0.005 sec (1/200)
Aperture: f/2.8
Focal Length: 140 mm

dual flash, one on camera, one off

the ultremos have been great to me so far. i have never gotten a flat with them but have found quite a few pieces of glass in them. none have them have made it through. they are ridiculously light, roll very fast and have good cornering grip.
