TTL and HSS on the RetraFlash

Fantastic TTL accuracy allows photographers to relax and rely entirely on automatic flash exposure control. Many creative tasks are made possible by using extremely fast HSS shutter speeds of up to 1/8000 with the Retra Pro flash in manual mode. The TTL converter firmware also has some other important updates related to its common functionality.

  • The Retra PRO profile can be set by the user üvia the TTL converter's built-in rotary switch.
  • The TTL/M modes can be switched underwater simply by using the camera name or the flash button.
  • In manual mode, the flash intensity can be adjusted manually üvia the camera wheel/scale, but also üvia the flash control knob.
  • (+/-) TTL flash compensation is supported by the firmware, the full range is available via the camera control in the range -3ev......+3ev.
  • The firmware supports sync settings for the 1-st /2-nd curtain and the rear curtain.
  • Continuous (serial) recording is supported.
  • The HSS firmware of the TTL converter supports the HSS functionality of the Retra Pro flash. The built-in 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. The Retra flash allows the HSS flash intensity to be set using the rotary knob.
  • In the updated firmware, switching to HSS shutter speeds is also included in the general functionality of the TTL converter (also for all other positions of the rotary switch), - usable for shooting with ambient light at high shutter speeds if required. However, the X-Sync speed limit (1/250 for Sony A7-A9) is still automatically supported for TTL modes, as required for mono flash TTL underwater flash.
  • Incredibly long battery life in the TTL converter: 1-3 years of continuous operation. The product has extremely low power consumption.
  • The converter features an automatic on/off switching module that saves battery power. No mechanical switch is required to switch UW Technics TTL converters on and off.
  • The TTL converter firmware includes TTL profiles for the following underwater flashes: 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 by the user üvia an onboard switch.

Light source This is a high-performance strobe that pursues quality of light, and its high luminous flux and wide beam angle are effective for wide-angle photography with fish-eye lenses and other wide-angle lenses. The strobe also features our proprietary light distribution technology. High light intensity GN33 The light output has a guide number (GN) of 33, one of the highest among general-purpose underwater strobes. The use of two discharge tubes increases power and achieves GN 33 at full flashing. Two discharge tubes Uniform and even light distribution The originally developed "aspherical toroidal lens" is placed in front of the light-emitting tube, and the two discharge tubes and the "aspherical toroidal lens" provide uniform and even light distribution to the periphery, making it an ideal light source for external Illumination. Aspherical optical troidal lens Adjust beam angle with diffuser The beam angle is 80°×105° without the diffuser and 100°×110° with the included diffuser for soft lighting. When the optional dome diffuser is attached, the beam angle increases to 150°×170°. The dome diffuser is effective when using a fisheye lens or when lighting with soft light (guide number is reduced by approximately -1.5 EV). Without diffuser With attached diffuser (optional) Dome diffuser installed Operability Sea&Seas particular emphasis on ease of use, especially underwater handling. The more you use it, the more you will appreciate its easy-to-turn dial, easy-to-see panel display, and good underwater balance. Large dial Underwater operation is performed with the mode switch and light intensity control dial. The large dials are non-slip and the height difference allows smooth operation even when wearing thick gloves. It is designed to stop in steps with a click-click to minimize malfunctions. Large dial Easy-to-read backlit panel The indicator color changes each time the mode switch is repositioned. Blue (in DS-TTLII mode), red (in RC mode), yellow (in manual mode with pre-flash), and green (in manual mode without pre-flash) are the different colors for identification, so positioning of the controls is easy to see even when night diving. In DS-TTLII mode In RC mode In manual non pre-flash mode Underwater Balance YS-D3 DUO by Sea&Sea has almost zero buoyancy with the ball mount and clamp in place. Heavy underwater weight requires unexpected force to operate the clamp, but the YS-D3 DUO is unaffected by buoyancy, so operation is smooth. Even if you change the strobe position, the underwater balance of the entire housing set does not change significantly and you can feel how easy it is to handle. Two patterns of target lights The LED target light function is useful for focusing and checking the beam angle of the strobe. Choose either 300 lumens or 150 lumens depending on the situation. 300 lumen 150 lumen One-touch battery replacement The power source is AA batteries, which are widely distributed in general. Four of the same type (1.5V alkaline AA batteries and 1.2V nickel-hydrogen AA batteries). The battery box is opened and closed by a bayonet type that does not put a burden on the O-ring. It is a one-touch operation and does not require force like the screw-in type. Hook for Fiber Optics A hook for fiber-optic cable on the strobe body smartly guides the fiber-optic cable. How to connect with the arm of your choice A straight type ball base is included, but the YS base or Strobe Ball Base 35 can be attached as an option depending on the application. (optional) YS base (optional) Diagonal ball base Accessories A wide variety of accessories expand the shooting range. Snoot An adapter that turns a strobe light into a spot light. An internal prism allows the optical axis of the target light to be perfectly aligned with the optical axis of the strobe light. The beam aperture is 25mm and the use of a snoot cuts off light around the subject to make only the subject stand out. Dome diffuser Diffuser that widens the beam angle to 150° x 170°. Light intensity is reduced by approximately -1.5 EV (GN28). Flash prism Light guiding prism that can emit YS-D3 DUO light without using a fiber-optic cable; supports RC mode and manual Emission.

Marine grade stainless and plastic parts complete the housing, and it is backed by a two year warranty against manufacturing defects. NOTE: The NA-A6600 is NOT compatible with (36206) N85 to N120 50mm Adapter. It requires the updated (36207) N85 to N120 50mm Port Adapter II. HDMI 1.4 OUTPUT With 4K HDR internal video recording and updated autofocus, pairing the NA-A6600 with an external monitor such as the SmallHD 502 Bright 5" gives video shooters a large, bright screen that features focus and exposure tools. HDMI 1.4 output requires HDMI Bulkhead (25032) as well as a supported monitor housing and internal HDMI cable (25076). WWL-1, CMC-1, AND CMC-2 Three in-house Nauticam optical designs, designed by founder and Managing Director Edward Lai, are the perfect lenses to complete an a6600 underwater system. The magic of the wet lenses is their tremendous versatility, paired with outstanding in-water performance. Both macro and super wide angle optics are available to the underwater photographer on the same dive. These lenses are completely engineered for use in water, providing the highest image quality available today in a wet mount optic. WWL-1 is a wide angle conversion lens, compatible with several lenses in the Sony system. The field of view is widest when paired with the Sigma 19mm f2.8 DN Lens, providing 130 degree diagonal field of view. WWL-1 is also an ideal match for the Sony E 16-50mm F3.5-5.6 PZ OSS lens providing over 100 degree diagonal field of view with full zoom through! With either lens on camera, class leading center sharpness, corner sharpness, and contrast result in the clearest wide angle images possible underwater. CMC-1 and CMC-2 provide the best macro performance available, with two different magnification strengths, suitable for a wide variety of macro subjects. With the popular Sony E 16-50mm F3.5-5.6 PZ OSS lens, CMC-1 is capable of capturing a macro frame 26mm wide, while CMC-2 captures an area 33mm wide. CMC-2 is less strong, making it easier to use with more accurate autofocus. CMC-1 is best suited for the smallest of macro subjects. Macro enthusiasts will surely want both! FAST AND RELIABLE FLASH TRIGGERING Reliable rapid fire manual flash triggering is available with the NA-A6600 for a variety of optically fired flashes when used with a new LED Flash Trigger (36315). The NA-A6600 comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Strobes and light arms can be attached to the housing via included 1? accessory mounting balls. The housing also features a cold-shoe and M10 threaded mount for a focus light or other accessories. Electrical strobe triggering (with power set manually on the flash head) is still an option for those with an investment in legacy lighting gear, requiring the purchase of an accessory electrical bulkhead. BATTERY PACK FOR NA-6600 HOUSING (2500MAH, INC. USB CABLE) (NA36332) The a6600 does feature a larger internal battery but especially when shooting video the benefit of an accessory battery pack greatly extends the time between battery swaps, and allows the housing to remain sealed between dives. The accessory battery pack rests securely below the camera inside the housing and provides power to the camera via USB. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is available with NA-A6600 as standard equipment. Combined with an optional vacuum valve (PN 25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur.
