Really the 100-400mm fits that bill.

The 300mm f/2.8L II or the 400mm DO II.
It will probably end up being the 300mm.

I debated for to long between the 600mm and 500mm II, I just couldn't make the decision.

I finally made the decision and today I am waiting on the big brown truck to arrive. I went with the 500mm II because of the size and weight.
That said the 400mm DO may be to close to the 500mm for it to be a contender.
I was hoping someone would get the 400 DO so I could see if it is a worthwhile lens or not. And I was kind of hoping it would be you because you are very thurough and particular in you assessments.

Go ahead... give it a try so I can live vicariously; and even better, find a problem so I can keep my wallet intact.
