I'm surprised I apparently haven't already chimed in on this particular thread. I own both a GW690ii and a GW690iii. I keep black and white film in one, color in the other, and regard these as perhaps my smartest camera purchases ever, even if my latest and possibly last ones. There's just a fixed 90mm lens; but the earlier interchangeable lens versions come out darn near as heavy as my Pentax 6X7 comparably equipped, and without anywhere near the same range of lenses, if you even still find them at all. These two camera have a modest amount of bulk, but don't weigh all that much. And they're so ergonomic that their easier for me, with my small hands, to shoot handheld than my NIkon. Great lens. I've had the older one out in some pretty bad weather for days on end. No problems. I pamper the iii one because I bought it nearly new, but still routinely go out and shoot it. The lack of an internal meter is no big deal. I use handheld Pentax spotmeters for everything anyway.
Around the same time as trying to decide about one of these, I had the opportunity to buy a clean demo GF670 at a reasonable price; but it just didn't feel right in my hands, and I was concerned about the scissor and bellows construction out in the weather. I also looked at a very clean M7 6X7 at a reasonable price. But already having a full Pentax 6X7 system, and coveting something with a longer 6X9 rectangle; for less that the sum of money for either of those, I got BOTH an excellent user GW690ii and a mint 300EDIF tele for my P67, which I had long wanted. I feel confident I made the right choice for my needs. Then I made a teak kitchen counter top for someone for the cash to buy the GW690iii (actually made quite a bit more than necessary for that - these Fuji "Texas Leicas" are a comparative bargain).
