All I can say is, I want one and how do some folks afford to buy one of these things?? I know that the lenses in your bag is what its about but when you start getting into the $1000-on up range..... wow, thats a little steep for me! I would be scared to even take this thing 20 feet away from any kind of body of water or anything! Probably just end up hanging it on my wall and showing it off to friends! I love shooting wildlife...how does someone justify buying a $5K lens? Probably when someone goes pro and gets paid for what they do.
