SIGMA MOUNT CONVERTER MC-21 EF-L for sale. I used it with a Lumix S1, but I'm selling it because I'm switching to a different adapter. The exterior shows signs of use, but there are no operational issues. AF and IS worked without problems. I believe all the accessories are included. Also, the firmware has been updated to the latest version. - Brand: SIGMA - Model Name: MOUNT CONVERTER MC-21 - Accessories: Box, instruction manual, warranty card, protective caps - Connection Type: Mount Adapter - Features: With electronic contacts Mount Adapter EF-L MC-21 Sigma
