Yeah, every time this thread comes up again, I get hit by a wave of jealousy.
I tried picking up a Moskva 5 a while ago to satiate the desire for a folder like that. The lens is nowhere near parallel with the body though; I still have it around to work on but as a user, it is a dud so far. The Zenobia totally sold me on good folders but it is 6x4.5.
Ugh. Stupid irrational jealousy.
