TTL-Converter for underwater strobes control for new NA-A7C Nauticam housing

Pavel Kolpakov, the inventor of innovative TTL flash control systems for underwater photos, shared information about the newest TTL circuit issued by his UW Technics brand. This product from UW Technics company is SONY compatible TTL circuit, – internal TTL Converter for Nauticam NA-A7C underwater housings, purposed for mirrorless full-frame SONY camera A7C.

UW Technics product #11078-HSS offers TTL and Manual exposure control of underwater strobes, also supports High-Speed synchronization (HSS) up to 1/8000s.
Easy user installation into Nauticam NA-A7C underwater housings
Products support most popular underwater strobes: Inon, Retra, Ikelite, Sea&Sea, and Subtronic

Combined circuit

The combined circuit, consisting of Optical TTL and Electric TTL system is on a single board with both triggering methods available both separately or simultaneously. High-Speed Synchronization (HSS) up to 1/8000s for “Retra” strobes is also available onboard.

Photographers can use fiber optical cable or Nikonos sync cord for underwater strobes, according to preference. Dual sync cords (Sea&Sea, Ikelite) are supported as well.

Easy User Installation

Installation is very easy and takes around 1 minute. The electronic circuit is fixed by a special metal mount and 2 bolts.

Powerful LEDs of the TTL-Converter are inserted directly into Nauticam optical bulkheads.

Installation is described in the User’s Manual included with the circuit.

Optional Electric Bulkheads

Optional electric bulkheads (with MicroMatch 4-pin plug) available for Nauticam housings (Nikonos, Ikelite, and S-6 style) are compatible with UW Technics TTL circuits. User can connect underwater strobes by sync cords, including dual sync cords. He has wide possibilities for assembling his own configuration of the flash control system, even can combine electric and optical TTL control for few underwater strobes simultaneously.

TTL flash lighting accuracy

Tests showed very good TTL accuracy in a wide range of camera settings. Users can change aperture, shutter speed, ISO, metering type, etc., but TTL-Converter automatically supports appropriate intensity flash lighting. The newest firmware contains an accurate TTL profile for each strobe type: Inon Z330 / Z240 / S2000; Retra Pro, Ikelite DS161 / DS160; Sea&Sea YS-D1 / YS-D2 / YS-250; Subtronic Pro-270 / Pro-160. Strobe type can be easily set by onboard miniature 10-position rotary switch.

No mechanical ON/OFF switch

UW Technics TTL-Converters don’t need any ON/OFF external switch. The device switches ON/OFF automatically via the camera command. This is a very comfortable feature for the user, he need not think about switching the device and need not have any mechanical switch on the housing.

Incredibly long battery life

Battery life: 2 years in continuous working mode. Products have microcurrent consumption from a pair of CR2032 batteries and an automatic ON/OFF switch. Users need not care about the battery during the dive trip.

Easy control via the camera menu

TTL circuit is fully controllable via camera menu, including switching: TTL / M, 1st/2nd Curtain sync, Slow sync, +/- Flash Exposure Compensation, Manual Flash Intensity Adjustment in M mode, Flash «Off» etc.

Comfortable flash intensity adjustment via camera menu

Manual Flash intensity 1/64 …1/1 adjustment is available, using camera wheel and camera scale.

TTL circuit firmware has a special module, which allows photographers to use 3 variants of M mode, including classic method and advanced method as well. Advanced control allows adjusting underwater strobe light intensity manually via camera scale (approximately 1/64 ….. 1/1). In this case, the photographer does not need to operate dial switches on the strobe body, he or she can just keep their hands on the housing, switch M mode, and set the flash intensity by camera controls.
