So I received my Mini TTi and Flex TT5 yesterday and have been testing and testing and testing. Here are some pretty exciting results all shot at 1/8000th of a second! I am using Profoto ComPact-R 300r's with the Flex TT5 plugged into one of those with the Mini on top of a Canon 5d Mark 2 to trigger it all. Then just for kicks I put up my old Vivitar 283's with some old 1970's era Wein slaves in the mix as well. As you can see from the behind the fan shot, all are being captured at 1/8000th of a sec. Feel free to check out the files and see for yourself if you don't trust my screen shots. They are also on the Pixelrust Photostream as well if you want more data. There does seem to be a touch of fall off on the camera right side of the frame but nothing that is a deal breaker.
I was chatting with the esteemed and accomplished photographer Mike Powell (they won't know I'm lying Mike!) and his thoughts on it are that the gear I am using is crappy (thanks Mike you jerk!) which means the flash duration is way longer then with good gear. So the actual strobes themselves are probably at around 1/500-1/800th of a second in duration which makes it easier for the Pocket Wizards to be in the sweet spot during the shutter release at 1/8000th. Go go crappy gear!
Also, this fan is called "Finga Choppa!" for good reason. This little guy moves at a good clip.
Also, these are test pics man, cut me some slack on the crappy lighting!
