Manfrotto make a neat little device that they call an Apron Support #166, it is a small open top bag that attaches and hangs between the legs under the tripod. It can be used to stow gear like meters/filters/film but can also be loaded up with rocks or water bottles or anything else weighty in order to help dampen vibrations. It's not the weight of the tripod that really matters, its more to do with the ground coupling which is a function of the total weigh of the tripod and load vs the rigidity and resonance of the assembly (depends very much on height too) plus the interface between the ground and the tripod. Too complex to simply say that the tripod needs to be 3 times the weight of the gear that it supports. > I bought the Zone VI to use under my view camera, but I could > probably use the 055 under it, as the thing is so light, and the > shutters don't cause any vibration at all.

My Mamiya 7 employs leaf shutters too, the vibration that it generates is minuscule which means that I have found I can get away with using a very light tripod and head as long as I don't have to contend with windy conditions.
