The only issue is that those white lenses tend to cost a lot less than the black counterparts. I'm not sure Nikon's spending that much more to make them. I wish they'd get on the par with Canon with regards to price in the long exotics. Also, maybe some slower, less expensive long lenses for those of us who can't afford a 500 f4. Maybe a 400 f4 and a 500 f5.6 for starters. Just a thought.
