These babies feel pretty good in the hand but what prevents me from using mine by hand w/o a tripod too often is two things. One, the long throw and more narrow DOF of the 6x9 format has it difficult to use fast for street photography. Two, unless you shoot at least 1/250th you will likely, through even minute camera shake, compromise the sharpness the these lenses can give. You will get acceptable sharpness but not the blow-away sharpness that they are capable of.
