I used to have a Mamiya 7, results cannot be faulted, but I did not rate the build of it. It's just pure plastic, and whilst that can be good, I just didn't like it. I traded for a Hasselblad, and I miss the Mamiya's portability, but the SLR of the 'blad is my preference for tripod shots vs. walking around shots. It's a really good camera if you don't mind that it does not look or feel anything like a Leica, Rollei or Hasselblad. My brother had a GF670, and that is a different beast entirely, if you don't mind the fixed lens, it is even more portable than the Mamiya and looks about as good as any camera I've ever seen. The bellows combined with modern features make it look like no other camera, and I just love it.
