I don't know whether these started off as RAW, but if as JPG the E1 probably
did its own postprocessing. Maybe it's programmed only to add sharpness and
contrast to digital Zuikos? ;-)

>From Gary's tests on the 75-150 @ 75 mm setting

  OM-1 with mirror lockup
  Notes: Very high resolution at the sake of contrast.

  OM-4T with mirror mirror and aperture prefire
  Notes: Moderately high contrast at all apertures.

Vibration reduction shouldn't change contrast for large objects unless we're
talking about an earthquake, so this may mean some samples have low contrast
and thus aren't a good general test of Zuikos on E1s.

It would be interesting to see a good 50mm tested against the 14-54 at 25mm.

For any Torontoids, Vistek has an E1 in rental now. Only $150/day. :-( The
lenses are more reasonable.

Mirror, mirror in the body,
Tell me which lens makes things gaudy.
