another plus is the higher number of elements that can give a better
overall correction. Not to say the lower speed. Imho prime lenses have
their advantages in lightness, compactness, brightness and in certain
instances macro capabilities.
Zuiko 100-200 f/5 zoom has a low number of elements and, according to
Olympus literature, can be duplicated successfully (that is a VGT in a
zoom).
