UW Technics releases new firmware with TTL-profile and HSS support for RETRA strobe
UW Technics releases a new TTL-Converter firmware update for Retra Pro strobe support. Firmware was created in cooperation and with the support of Retra company, Slovenia.
Currently available versions for Nauticam underwater housings: TTL-Converter #11075-HSS (for Sony A7-A9) and TTL-Converter #11073-HSS (for Sony A6000-A6600).
Fantastic TTL accuracy allows the photographer to relax and totally rely on automatic strobe exposure control. Many creative tasks become available by using extremely fast HSS shutter speeds up to 1/8000 with Retra Pro strobe in manual mode. TTL-Converter firmware also has some other important updates, which refers to its common functionality.
- Retra Pro profile can be set via the TTL-Converter onboard rotary switch by the user
- TTL/M modes can be easily switched underwater by camera menu or by the strobe knob
- In Manual mode flash intensity can be set manually by the camera wheel/scale, but also by the strobe knob.
- (+/-) TTL Flash Exposure Compensation is supported by firmware, the full range is available by camera controls in the range -3ev….+3ev.
- Firmware supports 1-st /2-nd curtain and rear-curtain synchronization settings.
- Continuous (Serial) shooting is supported.
- HSS firmware of TTL-Converter supports Retra Pro strobe HSS functionality. The onboard rotary switch must be set to the Retra Pro profile (position – «7»). Available HSS shutter speeds for Sony A7-A9: 1/320 ….1/8000 sec. Retra strobe allows HSS flash intensity adjustment by the knob.
- In updated firmware the switching to HSS shutter speeds is also included in common functionality of TTL-Converter (for all other positions of the rotary switch as well), - usable for shooting with ambient light when necessary at High Shutter Speeds. But the limitation of X-Sync speed (1/250 for Sony A7-A9) is still supported for TTL modes automatically, as necessary for mono-flash TTL underwater strobes.
- Incredibly long battery life in TTL-Converter: 1-3 years of continuous work. The product has extremely low current consumption.
- Firmware has an automatic On/Off switch module, which saves battery energy. No mechanical switch is needed for power On/Off for UW Technics TTL-Converters.
- TTL-Converter firmware contains TTL-profiles for the following strobes: Retra Pro, Inon Z-330/ Z-240/S-2000, Sea&Sea YS-D2/ YS-D1/ YS-250, Ikelite DS-161/ DS-160, and Subtronic Pro-270/Pro-160. Each profile can be easily set via an onboard switch by the user.
- Full compatibility with all SONY mirrorless cameras, independently of the model and TTL-protocol version.
