How to add HSS Sync to the latest cameras using PocketWizard Flex system

Nikon D4, Sigma 120-300mm ƒ/2.8 DG OS HSM | S, Sigma TC-2001 2x, Nikon SB-900, Nikon SB-800, PocketWizard Transceiver TT5, PocketWizard Mini TT1, AC-3, ISO 6400, ƒ/10, 1/2000

Getting this type of photo of the hummingbird I used the PocketWizard Flex system to help trigger my Nikon SB-900 and SB-800 flashes using TTL HSS.

I started to shoot this with my Nikon D750, but it wasn’t working. I quickly realized the PocketWizard system wasn’t working with the Nikon D750. That was easy to fix.

I fired up the Macbook Pro and plugged my PocketWizard TT5 and later the mini TT1 and updated the firmware to the latest version.

In case you wonder what is up with the green tape, I use it to help me know which channel is assigned to that PocketWizard.

I have the small Mini TT1 on the camera with the AC-3 on top. I have A Channel marked Orange and C Channel marked Green.

First thing I had to do was update the PocketWizard Utility to the latest 1.58 version.

While on the website to update the Utility I noticed the list of all the hardware and the latest firmware. You can click on the release notes to see what they improved.

Once I downloaded the software I then had to install it.

Then the PocketWizard Utility alerted me to download the latest firmware. I had the PocketWizard TT5 plugged in so it knew which firmware I needed.

After the update the Utility shows you a picture of the device you have plugged in with serial number and gives you all the specs including which firmware version is installed.

Now I can easily use the system with my Nikon D750 which was newer than the PocketWizards, thus the reason for the need for a firmware upgrade.

PocketWizard’s newest firmware platform taps into the camera’s digital communications to enable an entirely new level of remote flash capability through our proven radio system. ControlTL allows remote i-TTL for Nikon CLS / i-TTL systems as well as Manual Power Control.  ControlTL firmware is configurable and upgradeable for “future-proof” continuous improvement.


Go to all the websites of your camera gear and be sure all your gear has the latest firmware. If you are not sure on how to do this just use Google and search for your camera gear and also add the word firmware.
