Have you ever noticed that in low light that when the lens stops down
you cannot get an accurate exposure reading because you are beyond the
meters rated sensitivity? That's what JCO's referring to. Open
aperture metering is more accurate because the meter is more accurate if
there is more light, even taking into account possible inaccuracies with
mechanical linkages.

Have you understood that the lens only stops down *momentarily* to
meter and again *momentarily* to take the picture, and that at all
other times it is open?
Just wondering,
