I used the HSS GN table from the flash manual earlier in this thread and came up GN6.2 at 1/6000th !! That's when a ' power snoot' might come to the rescue, but only covering a very narrow FOV.

Generally in sunshine I find I'm only really needing to reduce ambient by 1.5 or 2 stops, so at wide apertures I'm usually ending up somewhere around the 1/800 - 1/1000th mark ... Not too bad for power really.

The Cactus has looked interesting for a while .... But I can't work out if you have to have the cactus flashes as well or can the V6 trigger our Pentax flashes ?
