I have a Littman as well. I love it. It is light weight compared to normal 4x5's, portable, and fits in a tamrac fanny pack. I Have a few (7) grafmatic backs, and I can get 3 in a Lowpro holder bag, (which goes on my belt), and one in the fanny pack. The fanny pack also holds my filters, and light meter. I can use my lighter weight tripod with it so no need to drag along the heavy weight tripod. I tend to use the rangefinder focus on it, so I leave the loupe at home. Down side is that it has one fixed lens. It alos doesn't have any real movements. Which for me works just fine, since I still need to get it blasted into my head how to properly use the movements without turning the camera into a pretzal.
