My acquired-2007 Olympus XA. It's the only camera I can carry almost everywhere, great shots, reliable. An xa and an xa4 will cover 95 percent of any photo situation I find myself in, though the xa4 is nowhere near as tough as the xa.
But I can't bring myself to get rid of my grandpa's old Zeiss Contina, or the Contaflex Prima I bought because it takes the same lenses (Rodenstock-made, it turns out, but very nice.). That Contaflex, not even top of the line in its day, has the best focusing screen I've ever seen, and the camera still works, even the 1 second ss, 56 years on. Just got to printing some shots I took 23 years ago with it-- tack sharp, and crisp like a potato chip.
If my Ricoh r-1 loaded the film on the first try EVER, it would be up there too. My first point and shoot, and the panoramic feature gets a lot of use.
