See post #2. But I should have included the 12mm as well, which I don't own.

However, in the interest of full disclosure, the O's pre frame-and-snap drill is perhaps the most unforgiving short-term memory test known to man. Good thing about this lens/camera is: just when you think you've mastered it, think you're really brilliant, you screw up and know you are, after all, simply stupid and unworthy.
Probably most of the folder cameras of the past that took medium format rollfilm were uncoupled, or had no rangefinder. There are some great accessory rangefinders out there, including Präzisa, Leica, Wattametter, Kodak, Voigtländer, et al.
More modern choices would be the ALPA 12 series, Fotoman, Gaoersi, or Horseman, though many are panoramic cameras. Then there are Fuji made choices like the 6x17 cameras, and the GS645W. In practice a wide angle can be more forgiving at closer distances to guess focus.
Roger Hicks has a great book out on Rangefinder cameras. Many of the cameras mentioned in that are scale focus, or perhaps more properly called viewfinder cameras. This book points out several good choices; adding an accessory rangefinder should be fairly simple, and will give that uncoupled experience.

Thanks for the plug. The thing is, quite a few RF cameras were also made in non-RF form (Leica I, M1, etc.) as well as RF form, and at that point it was quite hard to justify excluding other direct-vision (DV) cameras. A title that made it clear we were including DV as well would have been unnecessarily compendious. Here's a link to a brief description of the book on our site:
Ignore the stuff on the site about ordering from Amazon. We decided not to go with them after all, because we'd rather promote small book-shops, and besides, Amazon's policies on dealing with authors are more authoritarian than we care for.
