I just switched to 8x10, and I have a Horseman view. And I intend to do field camera work with it. That camera is a MONSTER. You can't carry it around on a tripod. Wish I had a field camera, but this is all I could afford. Having said all that, when I think now of a 4x5, it sheds a whole new light on the question. In comparison, ANY 4x5 would be acceptable to me as a field camera. A Calumet is one rugged as heck 4x5 and has all the movements.
