It's a gray market version with 1 year seller warranty.
One of the more popular and positively reviewed lenses for the Sony A7 full frame series.
(Side note: Sony has announced a new 50/1.4 e-mount lens. Also, the $699 price for this lens comes around every couple months from different eBay import sellers so it's definitely not uncommon.)
But-- if you're eligible, there's a YMMV ebay bucks promo currently, which would make this a pretty good deal.
