Part #: Nau-26321
The Canon TTL Converter is a Hotshoe mounted "mini" flash designed to trigger underwater strobes. Finally, you have the ability for TTL shooting with your Nauticam housing and fiber optic cables!! This Canon TTL Converter is capable of very fast recycle times, and can shoot in manual mode (set via the camera's External Speedlite Control Menu, see below). When shooting in manual it can keep up with the full continuous shooting frame rate of the 1DX II camera at 14 fps.
The TTL Converter is compatible with the following Nauticam housings:
Nikon users have had this all along, but for a Canon shooter this is a big, big deal... Very few (reliable) flash systems over time have allowed Canon 2nd Curtain flash synchronization, a critical functionality for dragging the shutter to create movement in a frame with motion blur.
In order to maximize the performance of this system, and flashes per charge, the Nauticam TTL Trigger for Canon is built around a compact rechargeable lithium ion Canon NB-13L and Canon CB-2LH Charger, which are sold separately. (Use the drop down menu above to add this battery and charger set)
There are some very important customer functions that must be set on your Canon camera before using the Nauticam TTL Trigger for Canon. Please follow these instructions when setting up the camera:
The Canon TTL Trigger has an automatic shutdown feature designed to save battery life when not in use. Most housings can't access the power button to turn it back on, so it is important to disable the camera "Auto power off" feature. As long as the camera is not metering, battery life is still very good even with this feature deactivated.
The menu "External Speedlite Control" tab contains a Flash function settings link which is handy for changing between TTL and Manual flash, and for setting First or Second (Front or Rear) curtain Flash Sync.
There is also an "Auto power off" tab for the TTL trigger, which should be disabled.
