Moose,
To start out, I was not really trying to do a lens comparison. I had
recently been shooting a 200mm Takumar on the E-1, because I happen to
like the Kodak sensor. Yes, it's only 5MP. But, for my purposes it
works Ok. I mentioned to a friend that the 200 FL was nice, but it sure
would be nice to have AF. He mentioned the 50-200, so I researched it
and bought one.
I had the lens for about 3 hours when I took the picture I posted,
obviously a mistake, because I had not really learned how to configure
the camera and lens properly. Rather than depending on "program", I
needed to pick a proper shutter speed and let another variable float.
My apologies for taking up your time with this.
As to the AF response to a moving airplane or parachute, I have had
similar difficulties with my Fuji gear, so it's not an E-1 problem alone.
I only have one other 4/3 body, an E-510, and it has only 10MP, which
doesn't help much, but also has a CMOS sensor, which has advantages, but
not in color quality when compared to the CCD of the E-1. One of the
main reasons I went to the E-1 is the robustness of the body, when
dealing with heavy lenses. This is not really a problem with the
50-200, but was a concern with my 200 Takumar.
Let's forget about this misbegotten comparison. I would delete the
image, but there are a few folks that always look at posts about 2 weeks
after everyone else, and would require an explanation as to where the
image went.
By the way, I also have several uncirculated sequential $2 bills in my
bank box. They appear to make nice subjects for resolution tests.

Might I suggest that there is no way to compare lens quality on an
E-1? If you see differences, it's in technique, not the lens.
I don't have a 50-200 for 4/3.*
I do have the first version 14-54. Herewith, same lens, same tripod,
same FL, same aperture. The E-1 may be a lovely camera, certainly
takes nice photos, but it just doesn't resolve much detail. Focus
magic used on all three image files.

The 14-54, OTOH, looks pretty darn good at 64 MP. My firm conviction
is that the 50-200 also vastly out resolves the E-1 sensor system. At
an informed guess, the Pentax out resolves it, too.
The Lens is Fine Moose
* I may even be prejudiced against it, as the first version is what
led me to choose Canon over Oly for my first DSLR. Not just slow to
focus, simply would not focus on a detailed, high contrast subject in
dim light. The 10D with similar lens focused easily and accurately on
the same subject.
