By Ian Bongso-Seldrup, October 2, 2019 @ 10:00 PM (EST)

UW Technics has announced a new TTL converter for the Sony a6000-series of cameras—from the a6000 to the a6500—in Nauticam housings. The new converter offers the same functionality as the recently released converter for Nauticam’s Sony a7 and a9 housings.

The user-installable board offers both optical and electrical triggering as well as both TTL and manual exposure control. The converter works with the following strobes: Ikelite DS161, DS160; Inon Z-330, Z-240, S-2000; Sea&Sea YS-D1, YS-D2, YS-250; and Subtronic Pro-270, Pro-160. A miniature 10-position rotary switch is used to set the strobe type.

Shipping now, the TTL converter is priced at $450.

Combined circuit

The combined circuit, consisting of Optical TTL and Electrical TTL system is on a single board with both triggering methods available both separately or simultaneously.

Easy User Installation

Installation is very easy and takes around 1 minute.

User’s Manual is included with the circuit.

Easy control via the camera menu

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

Special feature for M mode:

Flash intensity adjustment in M mode, using camera wheel and camera scale

TTL circuit firmware has a special module, which allows the photographer 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). This case photographer does not need to operate dial switches on the strobe body, he can just keep hands on the housing, switch M mode and set the flash intensity by camera controls.

TTL Accuracy

Tests showed fantastic TTL accuracy in a wide range of camera settings. The newest firmware contains an accurate TTL profile for each strobe type: Inon Z330, Z240, S2000; 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 switch ON / OFF

UW Technics TTL Converters don’t need any On/Off external switch. The device switches On/Off automatically by 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 is 5 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 a dive trip.
