Service: Service Concept

Does the camera define the value of your lenses?

The lens you have chosen amongst the others has been used to capture various scenes. The quality that makes taking exact shots you desired possible, the handling you are so familiar with – we are sure that these elements have become a unique character of the lens and have made you feel an even deeper attachment.

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.

Although lenses are the key devices to create photographic expression, it is a shame that there is no system that purely sets the standard based on the functions and individual qualities of interchangeable lenses.

A lens is your precious resource. Carry it with you longer.

SIGMA has never stopped thinking of ways to create lenses that ensure photographers get the shots they desire and to use for many years, and that they truly require for their own photographic expression.

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.
* This service will be available from September 2nd, 2013

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”.
