To all the experts & 5D Mk. III users out there, what do you use to trigger your strobes? I'm particularly interested in solutions to use Sea & Sea YS-D1s or YS-110 alphas with the 5D Mk. III in a Nauticam housing. Apart from using electrical sync cables with only manual control possible, is there any solution for TTL?
Also is TTL control possible with the strobes above on a fiber-optic connection? On my 7D, TTL works very well with the built-in flash. Since the 5D does not have a built-in flash, is there any TTL converter or adaptor in the market that will work with fiber-optic connections?
Thanks in advance for any suggestions.
