Between Mamiya C330/C220 and RB67, which one has better reliability and sharper lenses? I have some folding cameras, but now I'm looking to buy a MF system that I can use instead of LF for travel. In order to be versatile enough for this, I need at least a wide angle and a normal lens, and the ability to focus closely would be good too. I also want a waist-level finder. Rangefinders are out because they don't focus close, don't have WLF, and some don't have interchangeable lenses (or I can't afford to buy multiple lenses). Pentax 6x7 doesn't have a WLF, but is otherwise tempting. I could buy a mamiya or bronica 645 SLR and it would be compact and I could get lenses for it, but 645 isn't that big, and I don't know how close they focus. Some of them also need batteries. Pentax 645 has no WLF. I could buy a Hasselblad, but they are expensive, especially if you need wide lenses. RB67 has WLF, lenses are cheap, and it looks like it focuses pretty close. It's also cheap. It's a big camera though. Mamiya C330 looks pretty good...wide and normal lenses are fairly cheap, has WLF, focuses close. It seems like it's just as good as RB67 only somewhat smaller and with parallax. What's the difference between the C220 and C330?
