SIGMA Mount Conversion Service

From 1 September 2013, we will be offering our customers a new chargeable service, the "Mount Conversion Service". As part of this service, we will convert the mount of the lenses in the Contemporary, Art and Sports product lines by replacing all relevant parts at the customer's request. The necessary adaptation and optimisation to the new camera with a different mount will initially be carried out exclusively at the Japanese factory in Aizu.

1st concept

The customer only chooses the lens based on its performance, not on the camera mount.

We believe that a lens is not only a key tool for photographic expression, but that it is also an important resource for the photographer. We endeavour to develop a lens system that meets the needs of photographers in every respect and that they can use and enjoy over an extended period of time. As a lens manufacturer with decades of experience and technical expertise offering a wide range of interchangeable lenses, we were able to realise this unique chargeable "interchangeable mount service", which will be available to customers from 1 September 2013. With this service, the mount of Sigma lenses from the C, A and S product lines in your possession can be converted to a different mount system depending on the specifications of the camera body.

Cameras with the option of changing lenses represent a superior system. They offer the photographer more creative possibilities, as he can use a wide variety of lenses as required to achieve greater photographic expression. However, each interchangeable lens is limited to a specific camera system due to its specifications. In other words, you can no longer use these lenses if you change your camera system.

Although lenses are the key to creating photographic expression, it is a pity that there is no system whose standard is based purely on the functions and individual qualities of interchangeable lenses.

Over the years, Sigma has produced an extremely wide variety of interchangeable lenses. By leveraging their unique expertise and in-house resources, they are able to provide their new mount change service, which can be performed on all interchangeable lenses in the new product lines. Sigma will change the current lens mount and the necessary internal components so that you can continue to use your favourite Sigma lens on another camera body. Thanks to this service, you can use your favourite lens for many years to come, regardless of which camera system you originally bought it for.

This is why the "Connection Exchange Service" has been available since 1 September 2013. The aim behind this is to offer photographers more freedom by allowing them to choose new camera bodies without having to worry about the conventional restrictions of the mount system, while still being able to continue using their current lenses by adapting the mount.
