I'm wanting to buy a lightweight medium format SLR for traveling... my husband and I are going on a 2 year backpacking trip and I just can't fathom not shooting film. I really want to shoot with an SLR but I know it's nearly impossible to find lightweight MF cameras that aren't rangefinders, so I'm just looking for some decent options. I know it will probably be impossible to find everything that I'm looking for, but here is what I'm looking for in order of priority: 1 *lightweight* (as much as can be for an MF SLR) and not bulky (or at least something that breaks down and can pack in a somewhat compact way) 2 *close focusing range (or an option of good close-up filters) with lens option of at least f/2.8 or shallower -- I shoot primarily portraits 3 *price range under $1,000.. but preferably under $600 4 *6x7 or 6x6 format (not interested in 645 or 690, but would maybe consider it) interchangeable backs would be nice but are not totally necessary. I love all-mechanical cameras and wouldn't mind something that is fully manual... I would actually be lower maintenance backpacking and not needing a battery. Not interested in TLR's (I already have traveled with a few different ones and I love them but they are not what I'm looking for for this trip) and I'm REALLY not interested in rangefinders (I know they are the most lightweight but they just don't work for what I like to shoot). Also not interested in 35mm. numbers 1 and 2 on this list are must-haves and the rest are preferences. I could definitely budge on price if it really were worth it! Thanks so much in advance!!
