I've been looking for a field camera for backpacking, since my monorail encourages me to just take my medium format instead of lugging it up a 4000ft mountain, but someone suggested I look for a compact monorail to retain the movements of a full monorail but to make it more compact. I found a nice clean Sinar F1 kit on CL for $650 with a Schneider Symmar-S 210/5.6 and a handful of other nick nacks. I'm going to check it out tomorrow, but does anyone have any experience with these in terms of portability? I'd like for it to fit nicely into a backpack and not be too much a bother to lug around. The weight is fine with me, I'm more concerned with size. Could you also comment as to the quality of the camera overall? I see that it is a budget Sinar, but does it come across as a budget camera in real-world use?
