I have been shooting LOTS of 35mm film lately (and have a rather large supply of it as well), but have the incredible Mamiya 7 system with 43mm and 65mm lenses that I don't use enough. I think I am one of those people that likes to "save" the good stuff for "special occasions". Well, I am headed on a trip - DRIVING, with my two boys (4 yrs and 10 yrs) through two states stopping at Carlsbad Caverns, Santa Fe, Angelfire, Durango, Silverton, Pagosa Springs and Mesa Verde. Some pretty amazing photo "ops" in my opinion... Since I'm driving, space is at a premium, and since I'm still handholding the 4 year old, carrying "stuff" is also at a premium. I will be at hotels the whole time, but there will undoubtedly be times when I'll be leaving some gear in the car (well, Suburban). I have stocked up on 120/220 film, and plan to make full use of my Mamiya system. Should I even bother with the Bessa R4A and 28/21 lenses? It's really small and light weight, but it will still "be there" in my mind (I will not leave it in the car unattended, so I would be carrying it with the MF gear) and of course, the $1500 value of the system being there is an added stress. Is it realistic to only take the Mamiya 7 with me for the whole 2+ week trip as my only camera? With 10 frames per roll (or 20 on the few rolls of 220 I have) will that be limiting to me? I don't intend to take a bunch of crap pics, so I am happy using MF, but just want to make sure that there are those of you that would be comfortable traveling with one system for a trip. (my boys each have a digi camera that they are bringing, too). I'm really leaning toward the one system (with extra batteries of course) with loads of film and a tripod/L bracket (and all necessary filters).
