I see a Subal now have the V2 TTL system on sale on their website. Anyone have any experience of it yet? Elmer? Pavel?
Yes, i tested that V2 board (white color PCB). It has very nice TTL accuracy. And the 100% power of underwater strobe is available for TTL control by that board, another words it has full-size TTL (!).
Certainly, full-size TTL is available only for fully controllable strobes.
Tested strobes: YS-250, DS-161, YS-D1, YS-D2, Z-240. The board has a switch for those strobe types.
There are 2 pcs Optical TTL outputs and 2 pcs Wire TTL outputs onboard. Also, there is 1pc wire TTL connector for Nikon land strobe, because Subal also produces housings for SB-910/ SB-900.
New V2 board supports +/- TTL Flash Exposure Compensation (by camera wheel), TTL/M modes switching underwater, Manual flash power setting by camera wheel (in M mode). These features already became a good tradition for modern TTL products. The same features exist in Nauticam #26308 board, UWTechnics #11031 board and External #13038 converter, Aquatica TTL board, Hugyfot TTL board.
