Mount Conversion Service
The Lens Mount Conversion service, available only from SIGMA
Sigma's Mount Conversion Service enables you to continue using your favorite Sigma lenses even if you decide to switch camera systems.
How it works
You can convert your SIGMA Art, Contemporary, and Sports lenses to a different mount, but only to a mount for which the specific lens is already produced by SIGMA. For example, if you have the 17-40mm F1.8 DC | Art lens, you can convert it between L-Mount, Sony E-mount, and FUJIFILM X Mount, since it's available in all three. Keep in mind that only lenses within the SIGMA Global Vision line-up are eligible for this mount conversion service.

MOUNT CONVERSION COST BY LENS
Converting your existing lens to a new mount costs less than buying the same lens again. Lenses eligible for this service fall into 2 different price tiers.
