The lowest value ISO range adopted by camera makers is usually the sensitivity just under which the sensor saturates for the optimum bias and ADC sensitivity. At this point noise will be optimal as will exposure latitude. Lowering the ISO may compromise performance as the sensor may have to be biased so as to reduce sensitivity to prevent saturation. If you need slower effective ISO ND filters are the go.
