Purchased this lens new November 2015. It's some of the best glass I've ever used, however my business is becoming more focused on work in tough environments where a studio/portrait lenses like this can't go. The pictures should answer any questions you might have regarding condition. It was just serviced and cleaned by Sigma, I will include the service receipt in the original box. $650 obo I'm new to this forum, just signed up to start using marketplace. I have a long history of perfect feedback on ebay and AR15.com under the same username (westford86).
