In Topic: Nikon D850 in Nauticam Housing flash sync speed

15 January 2019 - 03:40 AM

A week ago at our office i tested D850 camera with the housing and DS-160 strobes, using TTL-Converter installed in the housing. That system had not original Manual trigger, but TTL-Converter pre-installed by dealer. So, this is not exactly your setup, but anyway ....

    I set normal sync speeds up to 1/250 (in TTL mode) by D850 menu, - lighting worked fine.  I also tried to set FP command by menu, to switch TTL-Converter to M mode as usual for such TTL-Converter, - everything worked fine. I did not see any difference in system work, comparing to other Nikon cameras.

     I think, it is possible to find the reason the problems regarding sync speed, if evaluate your concrete setup. Maybe the reason is self-made optical cable, maybe manual trigger, maybe camera settings , etc.  I can help. We can discuss the system in messenger, if you want.

Hi Pavel !

Thank you for your input :)
My TTL converter is the SKU#26308 and only has two switches on the board (no rotary switch).

No problem, this is just another version of that board, it has another switch type. This board is also fresh version, firmware can be updated.

Currently it supports the following strobes: Z-330, Z-240, YS-D1, YS-D2, YS-250, DS-161, DS-160.   

Retra Pro strobe ttl-profile will be available and will be added to firmware of all TTL-Converters, when this strobe is available. We will ask Oskar to lend a pair of samples, for ttl-profile tests.

If you want to update your board firmware by any new profiles (i mean future strobes on the market, like Retra Pro), you can contact Nauticam, send the board to manufacturer for update, for some fee. 

The same way is available for UWTechnics TTL boards update. It is available for some fee. Contact manufacturer.

If there will be any questions, contact me, i can help too.

..... does the new strobes will support the latest Nauticam TTL converter ?

I can help answer this question, if Oskar permits me.

Nauticam #26308 TTL-Converter will support Retra strobe TTL, when this strobe appears on the market. Retra strobe TTL-profile is planned to be in Converter firmware, set to position "9" onboard rotary switch.

Right, but are there any triggers (or, for that matter, cameras with a built-in flash) currently on the market that are capable of this?

I can confirm, UWTechnics company is ready to open HSS option in TTL-Converters firmware. It will be done the same time when Retra HSS strobe appears on the market.

UWTechnics TTL-Converters load full data of Shutter Synchronization (including HSS parameters) to camera brains and graphic menu. For Canon cameras it looks like this:

Hi Pavel.
Does this trigger support second curtain sync with Canon cameras?
I have read some where that canon cameras second curtain was only possible with Canon Speedlight strobes..

I can confirm, that product supports second curtain, it works. This TTL-Converter is intellectual device, the same level as original Canon Speedlights. It supports all Canon cameras, independently of model and TTL-protocol version.

Here is the picture of available 1-st/2-nd curtain settings, which this TTL-Converter loads into the camera menu:

UWTechnics TTL-Converter for Canon fully supports camera menu for external flash control, saves all these settings in onboard non-volatile memory, automatically load settings to camera menu and to camera brains during communication.

Many useful features are available via that TTL board, for example possible to switch to M mode by camera menu and adjust underwater flash intensity manually by camera scale. It gives more wide and accurate manual adjustment, than underwater strobe dial switches.

I am not sure, but suppose these are the single TTL-Converters on the market which support Canon menu so deep.
