Sigma to Launch New Mount Conversion Service

Sigma Lenses at CES 2013-5

Sigma is launching a new mount conversion service for its line of Sport, Contemporary and Art lenses. The service will allow customers to have lens mounts converted to/from Canon, Nikon, Sony, Pentax and Sigma mounts. Current eligible lenses include the 120-300mm f/2.8 DG OS Sport (shown above), the 35mm f/1.4 DG Art and the 17-70mm f/2.8-4 DC OS Macro Contemporary, among others. Additionally, Sigma lenses for mirrorless cameras can be converted between Micro Four Thirds and Sony E-mount options.

The mount conversion service will launch on September 2, and will range in cost from $80 to $250, plus shipping. Mount conversion requests will be taken at your local Sigma subsidiary. US customers should visit Sigma’s US website for conversion requests.

In addition to the new mount conversion service, Sigma is also extending the warranty of all cameras, lenses and flashes purchased after July 1, 2013 – to 4 years.

    Cool idea but probably a bit expensive to be worth while on anything but extremely high priced lenses. Let’s say they charge me $100 (that’s the low end) to change my Sigma 35mm 1.4 from Canon to Nikon plus shipping. Instead I could sell my lens slightly used for about $150 less than I paid and get a brand new Nikon version with free shipping and no tax from Amazon/Adorama/BH. Plus I would now get a 4 year warranty on the new item and completely break even since the repair + shipping will be at minimum around the $150 I would loose selling my 35mm 1.4.
