Mount Conversion Service

Change your mind? Change your mount. 
Introducing Lens Mount Conversion, only from SIGMA. 

We believe that a lens is not only a key device for photographic expression, but also an important resource for photographers.
It has been our hope to develop the lens system that is genuinely photographer-centered, and you can enjoy it for a longer period of time. 
As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, our desire and know-how is crystalized in this unique paid service, “Mount Conversion Service”*. With this service, the mount of your owned SIGMA lenses can be converted to another mount system, depending on the specification of the camera bodies. 

Interchangeable lens camera systems appear to be superior in offering photographers more options, allowing them to change lenses freely and have more flexible photographic expression. Nevertheless, each interchangeable lens is limited with the specification of different camera systems. In other words, you can’t use those lenses if you change it from one type to another. 

As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, we are proud to introduce the “Mount Conversion Service”. With this service, the mount of your current SIGMA lenses can be changed to another mount of your choice. This service gives a new life to your favorite lenses when you wish to use it on a different camera body. 

To ensure your lenses remain yours to use for many years. 
To achieve a lens system that reflects your preference and interest. 
We hope you will make use of the SIGMA “Mount Conversion Service”.
