Normally DO would be a nice addition, but the 400 f/4 is now $1000 more expensive and produces uncontrasty and unsharp images wide open; and many photographers stop it down, effectively wasting $4500. A normal, 400 f/4 prime with IS for $3000-3700 would be my next lens in a heartbeat. I'm still dreaming.
