I believe he is probably referring to the floating group/element. eSIF say, "It
incorporates a floating element group
for the first time in the world for a telephoto, ensuring superior image
quality even at close distances."
Also, we don't know which version he has. The 85/2 had the biggest redesign I
know of for a production OM Zuiko, going
from 6 elements in 4 groups to 5-4.
Perhaps the effect he comments on was a thing corrected.
