Much appreciation Sandy for your fast response.
In fact, I work with 6x7 kit, not 6x6 (Bronica GS-1 is 6x7 SLR system). I guess the main usage for 6x9 rangefinder would be landscapes, right ? That prescribes quite intensive usage of filters (at least polarizer and GNDs), so how it hanldes with GW69III bearing its rangefinder nature ? I would be glad to hear your personal experiences.
Also, what is shon on the counter ? History of the shutter activations or films ran through the camera ? What is the average life span for their shutters ? (what would tell you numbers of 100 or 500 on the counter ?)
