Graham, Eric, Barnard, Doug, Torger, Ken, Geoff and all others who chipped in,
Some great information here.... amazing how simple discussions can change the state of your mind.
Will be hunting for some local photo-outings and expeditions centering on MF... not sure there are many in Australia.
Met a guy called Ken Duncan the other day, has a good website, nice guy, but people have said he's a bit commercial.
on cameras, I've now added Linhof Techno to the list. Arca is quite severely limited in terms of availability, so is looking like it will be out.
So For now, it will be Alpa / Cambo / Linhof for a 3 lens kit, back, camera and bag.
Thanks for all the information, I feel better prepared and more in touch with the subject.
But yes, will have to handle a few machines before deciding.
