Sigma Adds Mount Conversion Service

Ronkonkoma, N.Y. — Sigma America introduced a new service on Thursday that enables the company’s Global Vision lens owners to change lens mounts for use on different camera systems.

Sigma also announced it is extending the warranty on all of its products — including cameras, lenses and flashes purchased on or after July 1 — to four years.

Previously, warranties varied by product. The enhanced product protection will provide Sigma’s customers with more consistency and improved service, the company said.

Meanwhile, the fee-based Mount Conversion Service will begin Sept. 2, when Global Vision lens owners can request to convert their current Sport, Contemporary or Art DSLR lenses to their choice of a Sigma, Sony, Pentax, Nikon or Canon mount.

Global Vision category lenses for mirrorless interchangeable-lens cameras (MILCs) can be updated to either a Micro Four Thirds or Sony E mount, Sigma said.

 “Professionals and amateurs alike are taking advantage of the many affordable camera options in today’s market; they’re updating their camera bags and exploring new systems and brands,” said Mark Amir-Hamzeh, Sigma America president. “When photographers purchase a lens, it’s often a significant, financial and artistic commitment — and we believe that investment should last a lifetime. Our new Mount Conversion Service and extended warranty are intended to help Sigma users get more enjoyment from our products, regardless of how their approach to photography changes overtime.”

The Mount Conversion Service is limited to all of Sigma’s Global Vision lenses. Current, applicable full-frame lenses include the 120-300mm F2.8 DG OS Sport and 35mm F1.4 DG Art; APS-C crop sensor lenses include the 30mm F1.4 DC HSM Art, 17-70mm F2.8-4 DC OS Macro Contemporary and 18-35mm F1.8 DC Art; and MILC lenses include the 19mm F2.8 DN Art, 30mm F2.8 DN Art and 60mm F2.8 DN Art.

Lenses can be converted to any mount of a photographer’s choosing, as long as Sigma has released that product in the requested mount.

Sigma said the fee for a conversion will range between $80 to $250, plus shipping costs, depending on the focal length of the lens.

All lenses will be shipped to Sigma’s U.S. subsidiary in New York, and updated, calibrated and optimized for the new camera system at Sigma’s factory in Aizu, Japan.

All lenses that undergo the Mount Conversion Service will be covered under warranty for six months following the update.

Teleconverters, USB docks and other accessories are not eligible for the service.
