Thanks David, Paul and others.
BTW, Paul, just few months ago I managed to round up my GS-1 lens lineup, so now I have 65mm, 100mm and 200mm lenses for GS-1 that pretty much cover my focal lenghtes needs.
However this GW69III still sounds quite tempting, too bad I have no a true MF-capable film scanner...:-(

BTW, do I understand corectly: GW690III doesn't provide cable release feature ?
