I have a Fuji GX680III, I can not imagine using it handheld, except maybe if you're shooting fashion and using strobes. It is far too heavy and bulky to use with anything short of the fastest shutter speeds. The way to use it handheld is to have the camera strap take much of the weight and use the waist level finder. Still this camera screams, "tripod".
