  1. You mean #26308 product (black color PCB). It did not have Retra TTL profile, no HSS support. Yes, for usage with Retra Pro, you have to replace TTL board.
  2. Hi Jose, Please check the User Manual of your TTL-Converter, If it already supports Retra Pro strobe (rotary switch position "7"), you have to update Retra Pro firmware up to V2.5 now.
  3. If you mean TTL board for Sony A7-A9, the hardwire was upgraded even in spring this year. Probably you have a last version hardwire. Anyway, let's contact by e-mail to specify some technical details.
  4. It is available to update this firmware for most of TTL boards. Please contact UWTechnics company for details by e-mail (uwtechnics@gmail.com). TTL boards manufactured since last summer have also some hardwire changes for better Retra Pro support and also this new firmware.
  5. I want to add some information for users, that UW Technics in cooperation and with the support or Retra team updated the firmware of TTL-Converters for Retra HSS and TTL support of this particular firmware version V2.5. So, all TTL-Converters manufactured last months are tuned for this new firmware.
  6. Hi John, MF-1 requires some more optical power for control than some other strobes. Buy this reason, for example, UWTechnics updated all their TTL-Converters, - specially for Backscatter MF-1 strobe better support. Optical power and pulse duration in M mode has been increased in all circuitry produced since September.
  7. Ok, but better ask manufacturer, what do those words mean, - Ys110a concrete separate profile exists in firmware (user can choose exactly only "YS-110a" by switch), or just "compatibility" at another strobe profile.
  8. Result will be the same with all manufacturers TTL boards, if YS-110a profile does not exist in firmware.
  9. YS-110a will work, but TTL curve is significantly different. As for me, the flash control will not be good enough. But that's up to you.
  10. Sorry, there is no YS-110a profile in that firmware. Firmware includes the following TTL-profiles: Inon Z240, Inon Z330, Retra Pro, Sea&Sea YS-D1, Sea&Sea YS-D2 (China version), Sea&Sea YS-250, Ikelite DS-161, DS-160 Subtronic Pro-160 Subtronic Pro-270.
  11. The "FLASH" symbol confirms that camera recognizes Nikon compatible device on the HotShoe and TTL protocol works properly. You have to begin with this. The other details mean nothing for a while, until you get camera TTL protocol working. Check all wires in system (5 wires from HotShoe plug to TTL circuit and power supply 2 wires: +6v/Ground from Ikelite strobe to TTL circuit). Check these lines also using measuring gadget, if available. When you are sure that all wires and connectors are normal, you have to think about TTL circuit board. Ikelite old circuits fail quite often. I have a lot of them in basket after repairs of Ikelite housings. If the circuit is failed, you simply have to change it to new. In common case, TTL system repair in Ikelite housing is not simple if you don't have necessary skills, better ask an engineer for it.
  12. Hi Tim, First of all, check if camera recognizes TTL circuit. If TTL protocol works, Nikon camera confirms it by the strobe symbol on the service screen.
  13. Hi Joss, Yes, if Retra strobe is in HSS mode, you can shoot at slow (normal) speeds too, using Nikon. But in common case, i would recommend to set Retra to M mode when use normal sync speeds, by 2 reasons: 1) In HSS position the flash intensity adjustment range (by another knob) is rather limited on both sides, it is acceptable for HSS pulsating flash, but user can not get Full power from the strobe, and minimum powers are limited too. So, when you don't need HSS, but use normal speeds, you can get a full range of available flash power, you have to use a simple mono-flash (set Retra to M mode). 2) In HSS position, but at normal sync speeds, the normal lighting is available only on Nikon cameras, because of Nikon simple X-sync for HSS flash. But on Canon / Sony / etc., there will be a dark strip on the image, because those brands use significantly different sync type/timings for HSS flash. So, this is also a reason to set Retra to M mode when normal sync speeds are in use.
  14. Hi Jose, You can look online User Manual for TTL-Converter #11031-HSS here: https://ru.calameo.com/read/005560836d01ae694dc7e I also can send PDF, if you give me an e-mail.
  15. Yes, of course, it works the same way on all versions of UWTechnics HSS boards. If user chooses "Auto FP" in Nikon sync menu, it switches system to M mode automatically. When shutter speeds are in limit up to 1/250, it works by normal sync mono flash. If use 1/320-1/8000 high speeds, then system automatically switches to HSS mode.
  16. Hardware is little bit different from previous boards. New HSS boards are much more powerful than previous, the LED output power is significantly increased. Such optical power is necessary for Retra Pro optical TTL input. Also, the firmware is new, it includes Retra Pro TTL profile and HSS support module. By the way, new TTL-Converter for Nikon (#11031-HSS) got updated TTL profiles of all other strobes too (Inon, Sea&Sea, Ikelite, Subtronic, Retra). This is totally renewed improved firmware.
  17. Hi Joss, UWTechnics #11031-HSS TTL board for Nikon is available now in online store: https://uwtechnics.com/index.php/online-store/ttl-converters/for-nikon/ttl-converter-for-nikon-nauticam-housings-detail New product firmware also includes updated TTL-profiles for Inon, Sea&Sea, Ikelite, Retra and Subtronic strobes. Available TTL boards for the following housings: Nauticam, Sea&Sea, Hugyfot, Seacam, Subal, Seafrogs (Meikon), Sealux, Aquatica. Today i tested this #11031-HSS board (for Nauticam) together with Retra Pro strobe at 1/8000 shutter speed, it worked fine.
  18. Not yet. We had some delays because of lockdown. Product will be available soon.
  19. Nauticam NA-D300s housing in excellent condition. It was used 2 dives in the pool, for lens tests. After that, it lay in the box. Housing condition is "like new". There are no any tracks of usage. Complete housing kit, including spare o-rings, tools, box and documents. Price = 500 USD. Payment: PayPal. Delivery: EMS, UPS, DHL.
  20. Currently only 2 items are left for sale: 1) Wide-angle 28mm lens = 300 USD; 2) Nikonos RS body = 250 USD. If both together, the price will be 500 USD.
  21. Fisheye 13mm reduced price - 2400 USD Wideangle 28mm lens - 350 USD, Nikonos RS body - 350 USD.
  22. I made a short video of 13mm fisheye and camera check:
  23. Hello Ian, Yes, the flooded item is already sold, deleted from list. Sorry. Currently i have only normally working items for sale.
