I read their little disclaimer thing but it was pretty general. I think i'm finally going to drop for the Nikkor 80-200 f/2.8 next week. I'm trying to figure out if the extra 40-50 bucks to buy from the US is worth it? It looks like the only real difference is a *possible* warranty thing. Anyone who has experience with this willing to chime in? If I buy imported... will the warranty be the same?
