I always use a tripod when I shoot my neutral gray card with a Summilux.
This allows me to use at f6.3 at 1/218th second, the optimum
non-light-falling-off aperture and the ideal shutter speed to avoid motion
blur. (Nothing worse than a blurry, dark cornered neutral gray card shot).
Ever wonder why Leica offers a Summilux M? I know why! Because its heresy
to use a tripod with a Noctilux. Plus, it's so massive and heavy even the
stoutest Arca ball-head equiped Gitzo can't keep it from toppling
foward. Therefore, it must be hand held.
