Voigtlander Bessa R-series camera are not so well-made when you are comparing to Konica Hexar, Contax G1/G2, Zeiss Ikon ZI, Leica CL, Minolta CLE class of camera.
Bessa use a much more lower-cost shutter assy as to cut cost. They are using a modified low-end Nikon FM10/FE10's (Cosina made those Nikon cameras also) shutter with extra set of shutter in front.
So you can't compare a Bessa R-series camera with any other cameras as I mentioned above.
