Sigma Announces a New Mount-Conversion Service and Extended Warranties

Share

Sigma has announced a very interesting new service available for all of their present and future Global Vision lenses. As of September 2, 2013, Sigma will offer a Mount Conversion Service through which you can send in your Sport, Art, or Contemporary series lenses and Sigma will change the mount to be compatible with another camera system. DSLR lens mounts can be changed to Nikon F, Canon EF, Sony A, Pentax K, or Sigma SA mounts, and mirrorless camera lenses can have their mounts converted to Micro Four Thirds or Sony E-mount. This service will allow you to continue to use your Sigma Global Vision series lenses even if you have decided to change camera systems.

As of August, 2013, the following DSLR lenses are eligible for this service: 35mm f/1.4 DG HSM (Art), 30mm f/1.4 DC HSM (Art), 18-35mm f/1.8 DC HSM (Art), 17-70mm f/2.8-4 DC Macro OS HSM (Contemporary), 120-300mm f/2.8 DG OS HSM (Sports). The eligible mirrorless camera lenses are all from the Art series: 19mm f/2.8 DN, 30mm f/2.8 DN, 60mm f/2.8 DN. Lenses that were never produced in a certain mount cannot be converted to that mount. For example the 120-300mm f/2.8, which was not made for Sony or Pentax mounts, cannot be converted to Sony or Pentax. All lenses that undergo the mount conversion will be covered by a 6-month warranty following the update.

Fees for theses conversions range from $80-250, depending on the lens, and shipping fees also apply. Lenses must be sent to Sigma's New York facility where they will then be shipped to the Sigma factory in Japan.

Also, Sigma has announced that they will be extending the warranty period on all of their photography products purchased from authorized Sigma dealers after July 1, 2013, to four years. Previously, warranty periods varied by product, and this enhanced protection is designed to offer consistency and improved customer service. This extended warranty applies to all U.S.A. products, including flashes, lenses, and cameras.

Can i have the17-70mm f/2.8-4 DC Macro OS HSM with a microfourthird mount.regards Herby

Hello,

Because mirrorless cameras have a shorter flange focal distance (distance from the metal lens mount on the camera to the sensor surface) than traditional DSLR's, adapting an SLR lens to a mirrorless camera body will require a spacer to make up for the longer FFD SLR's need.

We have a nice selection of adapters for converting Nikon or Canon mount lens to the micro four thirds lens mount.

Can you change this lens in a mft lens? Sigma EX DG 2,8/105 mm Macro FourThirds
