I have a Nikon 200-400 f4 VR (US) which I purchased around 7 months ago from Adorama, and other than testing it locally and taking it on a two week Namibia trip it has remained unused.
I am looking to exchange it for a Nikon 300 f2.8 VR US model in equally pristine condition.
Sounds like a nice deal for someone wanting the versatility of the zoom. I was forced to make a choice last Spring
between the two and wound up keeping the 300 f2.8 VR. Awesome glass. GL, Deb
