Not saying the lens doesn't have merits, just that it's not going to sell to more than a handful of people in the m4/3rds camp whereas Canon, Nikon (maybe Sony) will sell a lens like this to
their considerably large pro segment.

Well, it seems that this lens is selling very well, so well that
Olympus can't meet the demand:
