Priolite Hot Sync text by Christian Anderl

"Fast movement with shutter speeds between 1/2500 and 1/8000 were no problem at all, and even with sunlight in the back, the 500ws from the MBX500 were just enough to get quite good shots. [...] In Portrait photography it is also great to have the ability to shoot with short shutter speeds sometims. Using the Canon 1Dx with the 85/1.2 at f2.2 needed shutter speeds about 1/6400 to 1/8000 in sunlight. To get the shutter speed down to 1/200 or 1/250 we would have needed a ND filter. Not that this is so bad, but Autofocus doesn´t like ND filters too much, at f2.2 you should be very exact with the focus and you want to see what you are shooting. With the MBX500 it was just much easier to get these shots with wide open aperture without any ND filters attatched. [...] But so far – this is a great strobe, filling the gap between expencive high speed strobes and small on Camera Flashes. No Cable, internal Battery, very portable. Shutter speeds up to 1/8000 are no problem for the MBX500 Hot sync. It works great, didn´t leave us hanging at any point (Even if we didn´t treat it too good to be honest and the wind was really cold up there)."
