How much for the Nikon 800? Probably that much +10% Canon premium
The Nikon AF-S NIKKOR 800mm f/5.6E FL ED VR Lens is $17,896.95 at B&H. And the most recent customer review of the lens reads: "I use it for landscape and wildlife. Nikon case and overall quality is excellent. The soft lens cap is the worst I have ever seen in 50 years of experience. It is hard to work with and does not seal well. I have replaced mine with a shower cap that is far superior in terms of cost, ease of use and effectiveness."
So don't throw away those unused shower caps, you just never know when they may come in handy!!
Wonder who voted over US$ 21,000!! And I wonder how much over he or she thinks it is going to cost!
