Mount Conversion Services for PHOTO lenses
Sigma will convert the current mount of your Sigma Global Vision lens to another of your choice. Sigma lenses currently from the Contemporary, Art or Sports line, in Sigma, Canon, Nikon, Sony, Pentax mounts can be converted to Sigma, Canon, Nikon, Sony or Pentax*. Mirorrless lenses can be converted to Micro Four Thirds and Sony-E Mount. They cannot be converted to either an APS-C or a Full Frame format.

*Subject to mount, parts and service availability. Not all products are available in Pentax and/or Sony Mounts. Please check the specific product page to check availability in those mounts. For available Sony FE mount products click here.

The conversion service will be handled by Sigma in Japan so upon receipt, your lens will be sent to Japan to be converted to the desired mount and returned to Sigma America, who will, in turn, ship it directly to you. The anticipated turn-around time for this service is four - eight weeks.
