Mount Conversion Service /

The Lens Mount Conversion service, available only from SIGMA

Sigma’s Mount Conversion Service lets you keep your favourite Sigma lenses even if you change camera systems.

How it works /

SIGMA Art, Contemporary and Sports lenses can be converted between lens mounts. For example, the 18-50mm F2.8 DC DN | Contemporary is available in three mounts: L-Mount, Sony E-mount and FUJIFILM X Mount.

Lenses can only be converted to mounts that the lens has been produced in. It is not possible to convert mounts on lenses that are not part of the SIGMA Global Vison line-up. 

Mount conversion cost by lens /

Converting your lens is more cost effective than buying the same lens in a new mount. Each lens that is applicable for the mount conversion service is sorted into three price tiers.
