The Oly takes teleconverters and I understand that the Pany does not. As you can see from my images, in good light the Oly 100-400 does very well with and without the TCs.

The difference between f/4.5 (Pany) and f/5.0 (Oly) at 100 mm is only 1/3 stop. I don't think this is important because most of us probably use a lens like this a lot more toward the long end, where the apertures are virtually identical, than toward the short end.

Also, keep in mind that at 400 mm, the f/6.3 of the either 100-400 is only one stop slower than the f/4.5 of the Oly 150-400. Considering that the Oly 100-400 is 20% the cost of the Oly 150-400 and about half the weight, I consider it to be an excellent bargain. Not that I wouldn't mind getting my hands on an Oly 150-400, I can't justify the cost for what I normally shoot.
