Canon 5D Mark III with PocketWizard MiniTT1 / FlexTT5 / AC3 ZoneController

posted in: Gear, News, Photography 8

For those unaware, PocketWizard has not yet updated the firmware for their MiniTT1 and FlexTT5 system to be fully compatible with the Canon 5D Mark III.

Since I just acquired the Canon 5D Mark III and use the PocketWizard TT1/TT5 system in conjunction with the PocketWizard AC3 ZoneController (as well as the PowerMC2 and AC9) with my Paul C Buff studio strobes (Einstein and Alien Bees), this is an issue for me.

There are a lot of reports on the Internet right now from people using the TT1/TT5 on a Canon 5D Mark III, but I never got around to testing the triggers on my own 5D Mark III body.

So today I took a few minutes and was able to determine that the TT1+AC3 will work on a Canon 5D Mark III to do the remote flash output control (controlling power output using the AC3 dials) with the Einstein and PowerMC2.

The TT1+AC3 appears to *NOT* work when trying to trigger or control the flash output of an Alien Bees B1600 with FlexTT5+AC9.

The interesting thing I found is that I was able to trigger the B1600 with FlexTT5 connected via mono-sync cable from the TT1 over ControlTL channels *IF* the AC3 Zone Controller was piggy backed on it. Without the AC3 on the TT1, it would not trigger the B1600+TT5 (mono-sync) over ControlTL channels, and only would trigger over Standard channels (which is how you would normally be forced to trigger a studio strobe since they don’t understand TTL signals).

The MiniTT1+AC3 will trigger a Canon 580 EX II SpeedLite with a FlexTT5, but does not appear to control the flash output.

Any attempt to adjust shutter speed beyond the Canon 5D Mark III sync speed (1/200s) to use HyperSync would result in the camera automatically bringing the shutter speed back down to 1/200s when the shutter button was pressed.

So basically, if you use Einsteins with PowerMC2 receivers, you will still be able to control remote flash power output with the TT1+AC3 on a Canon 5D Mark III. All Alien Bees with TT5+AC9 and 580 EX II with TT5 will not respond to AC3 ZoneController adjustments.

Note: For these tests, firmware version 6.000 for the MiniTT1 and FlexTT5 (Canon units) was used with PowerMC2 firmware version 2.200. These are the latest production release firmware versions as of 2012-04-07. Check the PocketWizard Support Download page for the latest firmware.

    Canon 5D MkIII and CE (European versions) of PocketWizard Flex TT5 and PocketWizard MiniTT1 Wizard. Confirmed HyperSync fails to work using any combination of TT1/TT5 TT5/TT5. Always reduces speed down to 1/200 on shutter release.

    Did not bother trying AC3.

    Have the new Canon 600EX-RT and think that the Wizards and old flashguns may be sold in due course. Hopefully PocketWizard will come out with a firmware update to solve this issue soon.

    I just shot this weekend with my 5D3 and TT1/TT5/AC3 setup with my 580 EXII’s and 430 EXIIs and didnt notice that it exhibited this behavior; I was able to control the flash power via the AC3 for both the 430 II and 580 II flashes.

    I did, however, notice that it would force shutter speed back down to 1/200th. (i wondered why it kept going back down when i would roll the shutter to 1/320th or beyond, and thought it might have been related to the light leak issue since I was shooting in bright sunlight).

    Maybe you could share some more info on the flash/camera/AC3 settings, and firmware versions you where using.
    I really got problems shooting with the same combination. However, it sometimes worked, most of the times the flash didn’t fire at the same time the shutter opened.

    Any news regarding the compatibility between products POCKETWIZARD flextt5, minitt1 and the new Canon 5D mk3?

    I thank you,

    I don’t have any early access to news from PW. I just know whatever everyone else knows.

    I’m having issues with my TT5’s 580 EX’s, and Einsteins with my 5D3 as well. I hope they fix this soon. Planned firmware roll out order:

    I’m having same issues with my TT1, Einsteins and 5D3…at least now I know it wasn’t operator error.
