I currently have the Sigma 19mm and realized I am more of a zoom type of person. I am returning it, but am looking to replace it. I don't like the way the kit lens 14-42 needs to be "unlocked" and for some reason I don't like the fact it zooms out so far for such a short zoom length. I am thinking of the 12-50EZ since it is all internal zooming. Amazon has the international version for $135. Any other options out there that are sub $400?
