>I have a 17-55 2.8G IF ED lens for sale that was purchased at B&H late in 2009..Does the buyer knows something that I don't, or is he trying to get my lens dirt cheap? I would appreciate any feedback, thanks.
Most lenses sold through Nikon US have "USA" engraved on the lens barrel. See if yours has this engraving.
Back in the day, the USA market had "EPOI" stickers attached. I was very careful to take care of my Nikon stuff so they stickers would last.
