Search the site for "folders" and you should find a few relevant threads. These are great little portable cameras, just to carry around for casual shots or for travel.
In medium format, I use a Voigtlander Perkeo II 6x6 and a Voigtlander Bessa II 6x9, and I've also got a Voigtlander Vitessa-L 35mm folder. Usually the Perkeo or the Bessa is in my briefcase.
I've also found the perfect tripod for these cameras--the Linhof Report. It folds flat, and the legs snap in place, so it sets up really quickly (the bottom two sections snap in one position only, but the top sections also have locking collars, so you can use them to level the tripod on uneven ground). It was designed for use without a head, but you can add a little ballhead for ease of use. I usually use it with a Linhof Universal Ballhead 1.
