PocketWizard Utility 1.58 / ControlTL (FlexTT5/Nikon) Firmware 3.700

PocketWizard Utility 1.58 Changes:

- Full compatibility for the Nikon D810, D4S, D610, Df, D7100, D5300, D5200 and D3300.

Nikon FlexTT5 ControlTL Firmware 3.700:

- Improved SpeedCycler operation with remote TTL flashes (remote manual operation worked correctly). Previously, Zones B or C would not be in sync if they were set to A on the AC3 ZoneController.
- Improved how the LED blinks at power up in a FlexTT5 with critically low batteries. Previously it would blink green using a pattern not associated with battery level. Now it just turns everything off and goes into an extreme low power mode so the batteries will be less likely to leak.

The following Nikon gear is now supported in this firmware release:

- Nikon D4S
- Nikon D810
- Nikon D610
- Nikon Df
- Nikon D7100
- Nikon D5300
- Nikon D5200
- Nikon D3300

IMPORTANT:

- FlexTT5 for Nikon Firmware Version 3.700 addresses compatibility with newer Nikon cameras and some improvements we have made since the launch of ControlTL Firmware version 3.400.
- When updating firmware, be sure to update all of your radios to the latest version. Your radios will only operate as expected when all units are using the latest firmware.
- Previously used settings or saved profiles may not be automatically reloaded after installing new firmware. Make sure to record any important settings before loading the firmware because the PocketWizard Utility will perform a factory reset once the installation is complete and your previous settings will be overwritten.
