Given that I know many folks never get the chance to go to DEMA (I get to go to again this year ;-)I would be willing to ask around if that would be of any help. Just post things that would be of interest and I will see what I can learn.
One caveat, I will admit I am complete newbie to UW photography. My main goal is to look at housings and get a better grip (no pun intended) on them and an UW kit. I have been following the Canon 5D postings and plan to ask about housings for it, perhaps someone will have a prototype there. I know a lot of other folks are wondering about the new Fuji E900 and housings for it.
Cheers,
Allen
