Are the LEDs on the converter attached to the board or are they off the board on wires? How do you align them with the two ports?

The LEDs are on a separate board that replaces the flash reflector.

I’ve also read about in-camera control of strobes (for example, Manual and TTL switching). Is that type of control available with your unit?

I haven't found a way to manually control output from the camera, but to be honest I haven't looked too hard so far, and Pavel hasn't written the user manual yet. Connecting the converter enables the 'wireless flash' option in FN -> flash menu, but I haven't seen additional options.

For what reasons have you chosen to use the UwT converter rather than the camera flash for TTL?

  • Access to full range of strobe power on my ST-100s (currently limited by on-camera flash)
  • More accurate TTL exposure
  • Burst capability on low power
  • HSS capability with Retra strobes (after they ship and Pavel develops the appropriate firmware; that will take a while)
  • Battery life savings - triggering by pop-up flash, I can do 3 dives with 10-18mm or 2 dives with 90mm; hopefully the converter will improve that as I don't like opening the housing to swap batteries while on a day boat. On liveaboards I generally change the battery after each dive, but on something like a small bangka it isn't really an option.

A few more questions, if you don't mind.

Have you been able to verify increased strobe power with the UwT?

What was your camera flash setting?

Thanks.
