Thanks again for all the advice. Is it realistic that the Harrison tent be packed and carried?

So, it seems there are two things to know about boards, Linhof is one and the other would be the shutter? I guess one is the size of the board and the other is the size of the hole?

Yeah step-up rings seem the way to go. Otherwise you end up putting small filters on a larger lens...probably doesn't work to well. I forget (I have a horrendous memory) what size my filters are for my Hasselblad...but could some of those even be used, if the set up is right?

Alas, I will do some searching for these specific questions. Tons of information. Thanks again Alan.
