US $50 off the Sigma 19mm or 30mm.

The Sigmas are new this year I think, so I don't know if there is any history to go by. I've only had my Nex-5n for a month or so as well, and this has upended my plans. I was waiting to spend on the 16-50mm in January when it came out, and then planning to pick up the 30mm the next year or so. I now picked up both the 19mm and 30mm, and will put off buying the 16-50mm till much later. Hopefully by then there will be some of the 16-50mm lenses on the used market, or maybe the street price will have dropped a bit on it. I'll probably sell 19mm at that point.

Thank you
Russell
