Looks very neat, Pavel. Fits Subal too?

Looks like installation is a breeze. I shudder when I think about installing or removing my old UW Technics trigger.

Thank you, Tim.

Subal threaded holes usually are situated too close to the central protrusion on the top of the housing, it would be impossible to install such device, but only bulkheads. Currently i see only the following housings acceptable for the External TTL-Converter installation: Nauticam, Marelux, Sea&Sea, Aquatica, Isotta, Ikelite, Seafrogs.

Yes, this device was specially developed to simplify the installation and improve the mechanical protection.

Pavel - 
Very interesting looking product!
Where will one be able to see that menu displayed? Integrated in camera menu?
Will it be compatible with FF DSLR Nikon?

This is a camera menu for external flash control. TTL-Converter provides intellectual communication with the camera, including the menu options. 

The Canon version menu is shown on the pictures above. TTL-Converter even saves the latest Canon menu settings in it's non-volatile memory (for the user's convenience), and then loads them into the camera the next time the TTL-Converter is connected.

UWTechnics produces such TTL-Converters for Nikon, Canon, Sony and Olympus.

Nikon DSLR cameras are supported of course.

This sounds very VERY interesting. Would love to have menu control over the controller!
Do you need any folks to "test" production models? 😉
Any thoughts on anticipated cost?

Looks very Good Pavel, I would guess this streamlines your model range a little as it will fit any housing with enough space to route the hotshoe cable.

 

Out of interest what is different about the Isotta and ikelite M16 housings that requires a different version - perhaps something about the way the o-ring seal is achieved?   There was a related question on this recently.

Chris, thank you!

The Ikelite versions of TTL-Converter (M16 and 1/2UNF) have a slightly different o-ring sealing than others and need a nut, the same nut as Ikelite bulkhead has. The nut usage requires much longer length of rear threaded part, than Isotta. Also, Ikelite version TTL-Converter has a lower overall height of external part of the body to reduce the shoulder of external impacts and avoid damage to the plastic housing. Isotta version has some greater height of down external part of the body because some housing controls or protrusions are situated too close to the threaded M16 hole.

    Sometimes, who knows, It may be possible to install Ikelite M16 version Converter on the Isotta housing, but i am not sure, and it will require the concrete housing check.

 

So, Isotta and Ikelite versions of TTL-Converter are different in the rear part of the body. We will publish all versions soon, you will see the difference on the pictures.
