Interesting argument here JJump about the 180mm. I have heard over the years that it is one of Nikon's sharpest lenses, and is it is noticeably lighter than the 70-200mm. I believe the 130mm DC and 180mm are the two sharpest lenses in the Nikon Lineup among others. The weight would be much less if you have primes such as a 50mm, 35mm and even a 85mm. As long as you don't mind not zooming and putting the work in with your feet :) Do you find yourself going wide much?
I sold my 70-200 VRII and noticed (and lived) in the same country as Kanuck. That thing is a beast. I sold it in Japan just a few months ago for about what I got it for, bought a flash, a 28 2,8 AiS, 180 ED 1,8 AiS, and a 105 2,5 AiS and still had cash left over to buy most of my way back to Sweden in the fall.
The 180 ED AiS is so much easier to use than the 70-200 VRII. It is less eye-catching. It is lighter. It is easier (but stiffer) to focus. There is no comparison between the heavyweight the 70-200 is to the wonderful 180.
Won't be going back unless my next job supplied me with it.
