Another question is just my thought of curious, on the zero adjustment hood there are Z mode and M mode, we know the Z is used for zero adjustment, what about the M mode? At what circumstance should I use the M mode?

M mode is for "measurement".  This is used when it is a very steamy or dusty environment (say a paper mill) and the operator is trying to protect the lens and doesn't have the integrated airpurge snouts we provide on our online systems.
