Remote triggers: TTL vs ETTL ?
I've been reading people's views on various remote triggers like PW miniTT / FlexTT, Radio Poppers, Cyber Sync.
I'm just wondering what is the difference between the ETTL and the TTL functionality so often mentioned. I think I understand ETTL capability of the new PW miniTT / Flex system.
I have four PW+II's so I'm leaning towards moving (slowly) to the Flex/mini route, adding one at a time as budget allows. Although I'd love to somehow switch to a significantly less expensive solution, it doesn't seem feasible now, since I wouldn't be leveraging my existing investment.
