Offhand, I can't think of any 6X9 format camera's that have in-camera metering (autoexposure).
I bought my first GSW690III from a fellow named Don Metz from Vancouver WA. Here is his Neon Highways series on PBase:
I did sell the GSW, as I wanted both the focal lengths and wanted to carry only one body. So, I went back to my G690 and 100 mm interchangeable lens. I closely watched eBay until I finally scored a 65mm f8 lens. Since my dark blind works on the G690, I now have one body and two lenses. In addition the 100 interchangeable lens is a touch longer than the fixed 100 on the GW models.
The 65mm did not have a finder, so am using the 65mm finder from my Mamiya Press.
