I have a broken Canon mount Sigma EX DC 30mm f/1.4.
The focusing group does not work- in either manual or autofocus modes. I've requested a quote- Midwest Camera Repair (http://www.midwestcamera.com/lens.html
), a Sigma authorized repair center, quoted me $160 to repair and clean the lens. I can include the email of the quoute with the sale.
Since I don't have a Canon crop body and don't plan on getting one soon, I'm letting the lens go cheap. First $80 gets it- shipping included. PM or email to my user name @ gmail.
