• Sends and receives signals with greater reliability because the firmware makes the radio more resilient to RF noise. 

• Doubles the range for triggering remote camera(s) and/or off-camera flash(es). This benefit is enhanced even more when using the Plus IIIe and Plus IVe radios in Long Range (LR) Mode where distances have been measured in miles.  

• Expands the number of Quad Zone Channels from 16 to 32.*  

• Dedicates 80 new Channels for triggering in LR Mode.*

• The FlexTT5 for Nikon offes compatibility for i-TTL communication with the Nikon Z Series cameras. 
  

*These features apply to the PocketWizard Plus IIIe and Plus IVe models only.

Available now:

• Plus III

• Plus IV

• FlexTT5 for Nikon

• PowerMC2 (FCC units only)

Future releases:

• MultiMAX II

• FlexTT6 for Canon

The E Release firmware is available for PocketWizard Plus III, Plus IV, and FlexTT5 for Nikon radios worldwide (FCC and CE) and the the PowerMC2 is available for FCC radios only. Be sure you purchase the correct version of firmware for your radio and frequency (FCC in North America and CE for most everywhere else.)  

Important note: Once you have upgraded your radio, it cannot communicate with a unit that has not been upgraded. However, you can reinstall the legacy firmware at any time and reinstall the E Release as many times as you like. 

The beauty of this update is that most current radio models are USB upgradeable. See list of radios in question above. If you are using radios that do not have a USB port, such as the PlusX, Plus II, or an older MultiMAX, you will have to purchase new radios to take advantage of all the new features available in the E Release.  

Currently all Plus III and Plus IV radios are being shipped with the E Release factory installed. Once upgraded, we refer to the units as Plus IIIe and Plus IVe. Some stores may still be selling radios that have the Legacy firmware. If you purchased a Plus III or Plus IV on or after September 1, 2019, you may be eligible for a free upgrade.Please see our wiki for more information.   

The FlexTT5 for Nikon and PowerMC2 are available as upgrades only. If you purchased a FlexTT5 for Nikon or PowerMC2 on or after February 20, 2020, you may be eligible for a free upgrade.Please see our wiki for more information.   

Yes and no.

A PocketWizard that has been upgraded to the E Release can only communicate with another PocketWizard that has also been upgraded to the E Release.

However, a PocketWizard that has been upgraded to the E Release CAN be downgraded to the Legacy firmware and will still work with other PocketWizard radios that have not been upgraded.

Once you upgrade to the E Release, the unit is licensed forever to the radio's serial number. You can connect the upgraded radios to the Utility and select either E Release or Legacy firmware at any time.

You will need to purchase a Firmware License for each radio you wish to upgrade. This firmware will only work with other radios that have been upgraded to the E Release, it will not work with radios that have Legacy firmware. You will need to upgrade at least 2 radios to use the E Release.

An upgraded radio's status LED will flash a special sequence of red/green/red/green when powered on to indicate that it has the E Release.  On the Plus IIIe and Plus IVe, you will also see all four zones on every Channel - for example on Channel 1.

• Purchase a license for each radio you wish to upgrade.

• Download the PocketWizard Utility and connect the radio you want to upgrade to an internet connected computer (either PC or MAC) via a USB cable. The process is simple and fast.  

• The license is assigned to the serial number of each radio and is non-transferable.
  

The E Release is a firmware upgrade that required significant engineering work and delivers valuable new benefits.   

Yes and No. If you are looking for i-TTL communication with the new Z Series mirrorless cameras from Nikon then you will need to upgrade your FlexTT5 for Nikon radios to the new E Release firmware. Otherwise, the E Release upgrade is purely optional for photographers that want greater range and reliability from their existing PocketWizard radios. You can continue to use your radios with the Legacy firmware. 

Yes! You can revert back to the original firmware at any time.

Once you upgrade to the E Release, the unit is licensed forever to the radio's serial number. It can be downgraded to Legacy PocketWizard firmware at any time for use with your other PocketWizard radios. Reinstalling the E Release can be done at any time with minimal effort.
