Not likely.
Lots of threads from you about TTL. Don't worry so much about TTL. Don't get me wrong, it is useful, but 6-12 months down the track you'll proboably be using Manual for OCF.
I don't know what IgssEMT is on about.To the best of my knowledge, TTL/TTL-BL will only function on hotshoe or with CLS. Pocket Wizards have come out with their Canon verion of remote firing with TTL, but not Nikon yet.
Just wondering if TTL/TTL-BL would work off camera with my cactus.
EDIT: Damnit! :x I have the sb600, not sb800.
