The lenses are not to blame -- the photographer is.
Spot metering is your problem -- skin is not middle grey, it tends to
be either lighter or darker. Assuming you're photographing
light-skinned people, your underexposure is, in fact, the camera
operating perfectly and entirely user error. When using spot metering,
you need to take your readings off of something that's middle grey.
A course on metering would probably benefit you.

My recent experience with *istDL shooting portraits and lenses from
EXIF spec. shows images are about 0.7EV underexposed. Shooting in RAW
it is easily corrected with UFraw but I wonder if lenses are to be
blamed. Should I perhaps use center-weighted metering instead of Spot
for these large objects like portraits. Oh, and eyes are always need
to be corrected to expose full magic in them.
