800mm f/5.6...lighter than 600mm f/4....nice!

I only foresee rich professionals and rich status symbol people buying the 800.  The little over 10 lbs and 18" length would be a chore for me to carry very darn far.  The darn thing would get hung up on the brush, I would fall down and break the darn thing ugh!!!  I beat Moose buys one.  Eighteen thousand dollars is ridiclous.  My 8.5 lb 500 is all I want to handle for hiking very far.
