I’ve recently switched to using PocketWizard FlexTT5 and MiniTT1 radios to trigger my Canon Speedlite flashes.  Even though I have had the Flex model since it first came out in 2009, this past month was the first time I used the TTL (through the lens) exposure control feature that these models are known for.  One cool feature is the ability to synchronize at very fast shutter speeds.

I did a quick test of this feature the other day when Julie dropped by the studio.  The above image was shot with a shutter speed of 1/1600 second using a Speedlite 580EXII for the main light and a 430EX for the fill light (both with shoot-thru umbrellas).  I had the MiniTT1 on my camera and a FlexTT5 on each of the flash units.  This high speed ability will come in very handy in the future when lighting motion shots both in and out of the studio.

Have a great weekend!
