Do you have a question about your MiniTT1 or FlexTT5? Check out these Frequently Asked Questions, compiled by PocketWizard tech support.

Is my camera or flash compatible with ControlTL radios like the MiniTT1 and FlexTT5?

Check out our Canon Compatibility and Nikon Compatibility pages for specific information on your gear.

In what order should I turn everything on?

Power everything on “from the top down.” Local flash, then transmitting radio, then camera. Next remote flash, then receiver. Wait 2-3 seconds between each step.

Why doesn’t my Canon camera fire the flash on the first shot following power-on?

With a Canon camera and ControlTL radios the first exposure after initial connection or power-on is the calibration shot. It is recommended that you take the calibration shot at 1/160. This initiates communication between the camera and radio. This shot will not fire remote flashes.

My Nikon camera won’t let me choose a shutter speed faster than X-sync! How can I use HSS/FP speeds?

Nikon cameras require that FP-sync is enabled to shoot faster than X-sync if they detect a TTL-capable device in their hot-shoe. Enabling FP-sync is done in the Custom Settings menu. Set “e1 Flash Sync Speed” to “1/250s (Auto FP).”

Nikon D600 users set your “Flash Sync Speed” to “1/200s (Auto FP).”

Note that some cameras may have different a different menu setting to enable Auto FP, and that some cameras are not capable of HSS/FP-Sync operation. Enter your camera model into this wiki’s search bar for more information.

Why is there such a long delay between shots when I use my FlexTT5 in a remote camera setup?

When a FlexTT5 is used as a receiver on a remote camera, attached to the hot-shoe and receiving on ControlTL channels, the radio cannot listen for an incoming radio trigger while also communicating with the camera's metering system. This metering system is active and communicating with the radio whenever the shutter and aperture are displayed on the top of the camera's LCD display. This shuts off after about 5-8 seconds, at which point you will be able to trigger the remote camera again. This mode of operation is useful if want a remote camera to relay a TTL signal to a remote speedlight.

To disable the communications that prevent the FlexTT5 from listening for incoming trigger signals, you can put the receiving radio into Basic Trigger Mode via the PocketWizard Utility, under the "Misc Tab." Once you've enabled Basic Trigger Mode and set the radio to receive on a Standard Channel, you should be able to trigger the camera as quickly as you can press the test button on the radio in your hand.

How can I increase my range?

Can I use the AC3 ZoneController and my ControlTL radios to control the power of my mirrorless camera?

Yes! You can use your radios to control the manual power of compatible remote speedlights with almost any camera – mirrorless, film, and other non-compatible cameras with standard sized hot-shoe mounts will work.

What’s the fastest shutter speed I can use with HyperSync?

The maximum attainable shutter speed with HyperSync that produces an acceptable image depends on a variety of factors, from the age of the camera, the age of the flashes, to the type of cameras used. You can use HyperSync with any cameras on the supported list, but to find out the maximum usable shutter speed your camera can achieve, you will need to do some testing with your gear.

When will you have TTL support for the Canon 1D X, 6D, and T4i? What about compatibility for the Canon 70D, Rebel T5i, and Rebel SL1?

Adding full TTL support for the Canon 1D X, 6D, and T4i is our firmware team’s #1 priority. Canon greatly changed the way they communicate up through the hot shoe with the 1D X and newer cameras, and we need to spend time reverse-engineering every signal that comes up through the shoe and writing new code for it. Because of this trial and error approach, we can't guarantee or predict when we will be adding TTL, but we are working on it daily.

We intend to build compatibility for the newest Canon cameras like the 70D, Rebel T5i, and Rebel SL1 as quickly as we can after providing full TTL support for the 1D X, 6D, and Rebel T4i.

When will you add compatibility for the Nikon D4s, D610, D7100, D5300, D5200, and D3300?

We are currently working to add compatibility for the newest Nikon cameras like the D4s, D610, D7100, D5300, D5200, and D3300. Unfortunately, when dealing with beta firmware, there is no such thing as a fixed schedule. We are working quickly to include expanded Nikon compatibility in a future firmware release, but it requires reverse-engineering the signals coming up through the hot-shoe of the radio. Once we have decoded the information, a lot of testing occurs. Bugs may present themselves at any point in this process, delaying the schedule. Just like Canon model, these new Nikon cameras are receiving daily attention from our engineers and firmware developers.

The ISO on my remote Nikon Speedlight is stuck at 200. What’s wrong?

This setting isn’t required for TTL operation on the remote flash and has no effect on exposure, so the radios do not transmit camera setting information like ISO to remote flashes. The remote FlexTT5 simply gives the flash a default value on power-up, which is ISO 200.

My remote speedlights don’t change their zoom when I zoom the lens on my camera. What’s wrong?

Zoom tracking is a feature for on-camera flash and would cause lighting errors if performed on remotes. Nikon and Canon native systems do not have zoom tracking for remote or slave flashes, either.
