Im new to the world of Pocketwizared's in the past I have used the Cactus v5's and loved them but now with the MiniTT1 and FlexTT5 there are so many new options! But also a few questions I cant seem to find the answer for. (for all my testing Im using 430exII)

I have read that at speeds below 1/100th rear curtan sync is enabled in the pw (confirmed in the configuration app) for testing i have set a 1sec ss however instead of rear curtan sync it is firing for both front and rear, is this an expected behaviour?
I have looked at the description on the pocketwizard site (external link) and if I tried that it would have two golf balls.

also with the hypersync (I hope im using the correct pw term) as I increase the shutter speed (50D) I get a perfect sync up to 1/3000~ then beyond that I do get a small soft black bar near the bottom of the image. dont get me wrong 1/3000 is amazing and I will probably never need flash beyond that and even if I did the bar is so small a very small crop would remove it, but I have read that there are setting I can change that may remove that... just cant seem to figure it out.


So far loving all the advantages of the pw system. even if I cant figure out these two minor issues it was money well spent.

the flash at the start isn't going to impact your shot - that's the ETTL pre-flash that determines what it needs to fire off for what it thinks is a proper exposure... and then you get your rear flash...

Flash timing can be tweaked in the PocketWizard Utility. Hook the PWs to your computer with a USB cable and have at it.

At 1/3000 you are in 'optimized HSS' rather than true sync. PW refers to both as Hypersync but that's a bit misleading. Look on the flash control panel; when it shows HSS you're in HSS. You can adjust the point at which HSS kicks in with... yup... the PW Utility.
