In my recent exposure to a Fuji GSW690III, I've come to discover that this great camera came in 6 variations.
The III series of camera was available in these combinations:
6x7 with 65mm lens
6x7 with 90mm lens
6x8 with 65mm lens
6x8 with 90mm lens
6x9 with 65mm lens
6x9 with 90mm lens
All of these cameras had the same body, just different viewfinder lines and film gates.
I wonder if others are making measurement errors?
Or is +/- 1mm on an 80+mm area within normal tolerance?
I could see either/both .
It has come as something of a surprise to me that the film gate size on Fuji cameras of same name is different. ...

I'd agree about the manufacturing tolerance being orders of magnitude tighter than a mm or two in variation. The film gate on my GW690II is a solid piece, and machining or casting wouldn't work that sloppily.Now, what you speak about is the difference of the actual film gate size on one and the same type of the camera, here GW690III. That is surely interesting. As another poster said, were it the same camera and a different focal length, a certain difference comes from the fact that a shorter focal length lens make a little bigger film print due to the fact that the vertical film gate is a little bit offset from the film.
Anyway, in no case can it be a manufacturing tolerance - those are in order of 1/100 mm, even more in this type of industry.
This is going to make me look like an idiot, but my conscience would bother me if I don't fess up to to the mistake.
Briefly, my measuring instrument had an additional three millimeters on the end before the 0 mark and I failed to notice it. When I realized this I went back and measured the negatives again, and got 56.5X85mm for those made with the GSW690III, and 56.5X83mm for those made with the GW690III. The gate of the GW690III measures 56X82.
Now I am going off the find a hole to hide in.

So, I am wondering if Fuji would be able to make the new GF model, in the same combos? The prototype is shown with an 80mm lens. Could they not just make the camera slightly bigger and offer a 6x7, 6x8, and a 6x9 model, all with the 80mm lens? Sure, the larger body might not fit in a jacket pocket but it is still very portable.
Hmmm......

Fuji did have a series of models in the late 60's and 70's that had interchangeable lenses. The prototype of the G690 (1968) had a switch for 645 at the film gate, but that wasn't in production models. The lenses were interchangeable between the 670 and 690 models, so you could either pick one aspect ratio, or buy two bodies and use whichever lenses you chose. You can read about them here: http://www.camerapedia.org/wiki/Fujica_G690To me, this begs a question: can't Fuji make a single camera that has different interchangeable film gates for the different formats (6X4.5, 6X6, 6X7, 6X8, 6X9)? Then either include a knob that lets you adjust the film counter to compensate for the different frame sizes and reduced or increased picture counts? Even have some form of interlock system so that the camera automatically compensates for the different film gates? Combine that with interchangeable lenses and you have one camera that can do it all.
All this talk about the G(S)W series and the Mamiya 7 II got my interest stirred up about a Rangefinder. I have only used SLRs in 35mm (Nikon 8008) and 6x7 (RZ67), then on to LF. Would some of you who have used folders talk about the advantages of folder VS RF, or the other way round? Moderators, if you think this should be a new thread, please move it.
Thanks,

John: The Fuji GSW690III Cameras and Mamiya 7 II cameras are fixed body cameras that incorporate lens coupled rangefinders. They are not folding cameras.
Sandy,
Interestingly, correcting your mistake makes you a bigger man than your ruler would indicate.
