My workhorse lens broke a leg and no longer auto-focuses correctly. I contacted the manufacturer, and it sounds like their solution is to sell me something - no warranty and whatnot cause it was bought used. :( I'd like to explore repair options if possible, but Google is now little more than a minefield of ads and I don't know who to trust. Can anyone recommend a service in the US? The lens is m4/3 for what it's worth.
