I agree that the Alpas are beautifully engineered and built cameras and I would love to own one because it surely has the bling thing going in a big way, but every time I think about it, I just cannot see a positive tradeoff between using the Alpa with a digital back for landscape work and a Hasselblad, Mamiya or Contax. On the plus side with the Alpa, I could achieve a bit more resolution with the best Rodenstock and Schneider digital lenses, though the degree to which this is observable in even large prints is probably debatable or irrelevant to the issue of whether the image is a powerful image. On the minus side, with the Alpa you cannot focus through the lens, so you are left with kludges like laser devices and the like. Oh, you can take the back off and focus through the ground glass? Very practical. Dust? Rain? Where do you put the back? Easy to see on the ground glass? Also, if you use Helicon Focus to bracket for focus, it's fairly easy to do the brackets focusing through the viewfinder. I cannot imagine pulling a digital back on and off 5 times to focus for my brackets. Composing? I had a Horseman SW612 with a 55mm Rodesnstock and found it VERY difficult to compose and to "see" using the non-optical Horseman viewfinder(or no viewfinder at all). With a "normal" focal length lens, this isn't much of an issue, but with very wide angle lenses and telephoto lenses, the lens significantly changes the look of the image.
