Depends on which Mamiya you are talking about. I sold my RZ because it was too big and heavy. My 4x5 is lighter, and because of the weight I wanted to use them both on a tripod all the time. The RB is even heavier. The 645 Pro TL is a very nice hand holdable camera, especially with the winder grip on it. The Hassy is in between in my opinion. The Mamiya 7 is the best hand holdable camera I have, including 35mm. The lack of mirror really helps, and I think it's more the mirror's effect on me and not the internal vibrations. Very close to what I imagine a Leica is like.
