Let me tell you where I ended up. First... hand held metering is a preference of mine. I like a little lens interchangeability. So I ended up shooting the old Texas Leica Fujica Rangefinders. Great glass.
I finally settled on the Fujica GL690.... The 67 counterpart is the GM690.
For two lenses focal lengths, I have the 65mm lens, and the 100mm lens. Both of these lenses can be used on the GL and the GM model bodies.
The GL and GM bodies are identical in size, but I opted for the 690, because I am more likely to shoot 690... same aspect ratio 2:3 as in 35mm film. I crop for 6X7, and overall, I only lose one frame on a roll of 120 by shooting the larger format.
I don't think the frame count for 220 enters into the decision, because I believe all the emulsions for 220 have disappeared????
The GL and GM models have two shutter releases. One on top, and one on the front for shooting vertical.
The big Fuji's have been an optimal decision for me, and how I shoot. The 690 format is not overly costly, and since the cameras are the same size anyway...well.
If I had the motivation to do more with 6x7, I would probably just get the GM body and since the lenses interchange, I could swap lenses and bodies.
ALL the GW and GSW lighter bodies come in 6X7, 6X8, and 6X9, with fixed lenses of 65mm or 90mm. But you would need four of those cameras to have the flexibility I would have with two interchangeable lens bodies and the two lenses.
However, you could carry two GW or two GSW fixed lens bodies at just about the same weight at one interchangeable body and two lenses.
An advantage with the GW choices would be the EBC lens coatings.
However, I am perfectly happy with the older coatings on the interchangeable lenses. They only made one EBC coated lens for the interchangeables... the Automatic Aperture Priority metered AE100 lens. Oh... I have that lens. Hmmm?
