bed bug: Do they support ETTL as per the Flex TT5 and Mini TT1?
I have used both Canon's eTTL and Nikon iTTL, both are good systems but I have experienced limitations. I found out back with a shoot in 2010 during a family shoot on a very sunny day. Both my SB900 and SB800 missfired several times.
I also know that Canon's new proprietary system won't work with my studio lights, so I would still need another radio set to fire them. So that is not the answer for me either.
Finally in November I purchased 5 pocket wizard TT5's, with a TT1, AC3 and AC9's. Now I can use my Nikon flashes with my AlienBee lights. Was it cheap? No but it gives me the versitility I need.
The new PW Plus III's even though they are not TTL, they give me 4 zones I can control manually. I currently have three with the TT5's. When I am shooting several subjects with different skin tone ranges and different colored outfits. I don't have to worry about constantly fusing with TTL getting fooled.
Yeah there are cheaper systems but durability is one reason I choose PW's.
