Kewl, you wouldn't happen to have an extra OM to E1 adapter?

I guess that also means more batteries are needed in the field.

Well, I do know if I set the E-1 aperture to as high as possible,
the dust is visible, but not nearly as in focus as it is on the
5D. One more advantage the E1 sensor size has, as the
mirror box dimensions for the FF 5D are probably tight,
while the E-1 has more room to add distance, which means
an even higher F-stop is needed to make the dust an issue.
