Is there a 24-28mm zoom??
I'll gamble and guess that it's the 28-48mm. From my personal experience, I'd
say that it's a quite reasonable zoom with good contrast. It only has 8
elements,
so there is not too much glass.
However there is one thing you need to keep an eye open for: Slack or wear in
the zoom mechanism, causing the focus to drift significantly when zooming. I
own three Zuiko zooms, all having this problem to some degree. One is decidedly
loose: The front with the focusing ring can be moved close to one millimeter
back and forth due to slack! Not my most reliable lens and one of the reasons
for my preference for fixed lenses.
Nowadays I'm feel I have to be extremely careful when considering a used zoom.
Fixed lenses are so much easier to judge due to simpler mechanics.
