The problem I have with this is that if I decide to use a different
meter in a particular situation, say for an incident light reading that
I'm using due to the needs of that particular photographic situation,
then a camera that gives a different meter reading (from my correect
meters) but corrects for it internally (presumably by giving an
incorrect exposure that compensates for the incorect reading by going in
the other direction) will not give the exposure I'm setting! So if my M6
suggest half a stop less, but gives half a stop more anyway, thus giving
a correct exposure when its internal meter is used, then it will give me
half a stop more than I want when I use another (correct) meter. Thus
the meter *and* the camera will need ajusting... Am I missing something?
