Hi Windsor:

> Why would you just pass up non-telephoto lenses that do not focus at
infinity?

I thought someone might ask.  Focusing past infinity is actually a feature of
some (many?) 300 mm and longer lenses.  Different ambient temperatures result
in focus shift.  Using a Varimagnifinder I've determined that even the 200 mm
f/4.0 Zuiko can focus shift, so I don't writte off a 200 mm or above which
won't get pinpoint infinity focus in a sales shop.
