Change Your Mind? Change Your Mount.

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

Sigma has made it possible to invest in premium lenses and have the freedom to change your camera system without replacing your lenses. You can use the Mount Conversion Service to change the mount of your current lenses to any other mount offered by Sigma for those lenses.

• All lenses from Sigma’s Art, Contemporary and Sports lines are eligible for conversion.
• All conversions done at Sigma’s Aizu factory in Japan to ensure the highest level of quality control
• Converted lenses are fully compatible with the new camera system, with no loss of performance or functionality.
• Each converted lens must pass the same rigourous testing as all of Sigma’s new lenses before it leaves the factory.
• Changing your mount will not affect the seven-year Canadian warranty on your lens.
• Available starting September 2nd, 2013 (a fee will be charged for each conversion).

Level 1 – $150.00
Level 2 – $300.00
Level 3 – $500.00
