I had the Tokina 11-16mm on my D7100, and it was fine. It was the U. S. version, and I paid $690 for it. When I sold the D7100, I sold the lens for $502. For the current Amazon price, I wouldn't be concerned about the warranty. I've been shooting since the 1970's, and I've never had a camera or lens serviced, except for the D600 sensor spot recall.
I have the Tokina 11-16 on my D7100 as well and love it. I got slightly used from eBay for $337. GREAT deal. I've seen others go for more. I wouldn't be concerned about warranty for lenses as long as you can return them initially if they don't work. If they work at first it's highly unlikely they'd fail later unless you abuse or drop them. And then the warranty wouldn't cover anyway.
