Originally posted by Stratman My cousin has the 300-800 in Nikon mount, and he loves it. It's friggin huge, makes his D3X look like a toy, haha. I think he said it weighs 15 lbs.
Heck with the Sigma, I want the 3-wolf-moon shirt!
Seriously though, lack of longer lenses and service of them drove me to Canon. When you are talking about a lens like that it matters little what brand body you have to stick on it. A couple years ago I got a 40d refurb and a 400mm f5.6 for the price of a used (with no service support) FA400 f5.6.
