The lens opening to sensor distance for the E-1 is close to
the distance in the 5D, while the 5D needs a full frame mirror,
hence there is not as much room to get the dust as far from the
sensor. The E-1 has more mirror box space and can afford
to put a membrane further from the sensor. That was the
advantage I was referring to. As usual though, everything
is a tradeoff.

I'm an engineer, I'm sure it was not genius that "stumbled"
upon it. We, as a lot, rely on dumb luck more often than not.
Genius can only be attributed to someone if they actually
realized they had something, after the fact.
