By the time this makes distribution on the OM List, I will have posted to:

the results of lens testing for the 50-250mm f/5 Zuiko. I used the Bogen
Long Lens Support with this one, since it is front heavy and not particularly
suited for tripod use (i.e., lacks a tripod collar). The zoom range is
breathtaking and it's easier to focus than I expected. There isn't much
depth to the lens hood at long focal lengths. Also, the lack of internal
focusing makes for lots of lens movement when using a Long Lens Support, thus
the need to clamp down the lens AFTER composing and focusing.
There is a dip in performance at the 200mm focal length setting. This is
real hard to explain. I double-checked focus AFTER clamping down the Velcro
strap, so I'm not sure what is up here. Another case of the OM-1 harmonics
at 200mm?
Noteworthy is an A grade in the center at f/16 and 250mm!
Posted in the competing lens section are the results of the Canon FD 35-105
f/3.5 constant aperture zoom - a much heralded lens. The 35-105mm f/3.5~4.5
Zuiko is no slouch in comparison.
