Re: [APML] Orion Short Tube 80

Steve,
You can look for the following:
Zuiko 300/4.5 $300.00 - $400.00 USD, used. 
Zuiko 400/5.6(?)$500.00 - $650.00 USD, used. Not as sharp as the 300/4.5.

Tamron makes a 300/2.8 and 400/4 in adaptall mounts. These are excellent lenses. 
I see them for sale anywhere from $1000.00 - $1600.00 USD, used, depending on 
condition, accesories.

The OM adaptall mount is around $25.00-$35.00.

If these are too rich for your budget try finding these lenses. 
Zuiko 200/4 - $100.00-$140.00 USD.
Zuiko 135/2.8  ~ $135.00 USD. (Beautiful lens).
Zuiko 135/3.5 ~ $50.00-$75.00 USD. (Not as fast as the 2.8, but sharp).
Zuiko 85/2 ~ $225.00-$275.00 (Another beauty!).

Zuiko also made 180/2, a 180/2.8, a 250/2 and 350/2.8 all extremely good lenses 
with extremely high prices.

Hope this helps,
Charles Packard
