I just picked up a sigma lens off eBay for $20. It is said to be in good condition, but the manual and auto focus do not work. Anyone ever have a lens repaired? How much was it? Is it possible to repair it yourself?
Contact the Ebay seller to get your money back - good condition definitely doesn NOT mean the manual and auto focus do not work. Paypal or Ebay will stand behind your purchase and get your money back for you. Contact the seller first. If they do not respond, start the resolution process to get your money back. Repairing the lens will most likely cost well over a hundred dollars (usually just the bench fee is 100 bucks). Good luck!
