"Nikon is decades behind Canon for fast lenses."
"Specifically, if I had less than $10,000 to spend for a digital camera system for landscape shooting, the system I really did use in Yosemite this past fall was my 5D, the 16-35 II and the 70-200/4 IS. Today, you can have these all for $4,275, much less than a single Nikon D3 body which isn't as sharp anyway."
"The 5D is sharper than Nikon's D3, for a fraction of the price. The 5D is the best digital landscape camera there is for under $8,000, and with rebate, it's only $1,900! The 5D wipes the D300, as well as the D3, for tripod use. I bought my own 5D in 2006 when Canon offered a rebate."

Real pros don't have websites. People with too much time on their hands have websites since they're not out shooting. This is why I caution everyone not to believe anything they read on the Internet unless they know the author personally.
