Interesting point, maybe someone with a *ist D can execute a multiple exposure of a static subject from a sturdy tripod at EI 3200 and compare the output noise with a single exposure? Other than noise reduction or shooters requiring direct print from RAM cards I can't see any other real use for the multi-exposure function.
