Sigma Announces Lens Mount Conversion Service (and 4-Year Warranty)

August 1, 2013

If you’ve considered changing up your camera system but are too heavily invested in lenses to do so, Sigma may have the perfect solution to break the bond you have to one brand or another. That is, if your optical stash includes lenses from Sigma’s Global Vision line

Beginning September 2, 2013, Sigma Corporation of America will offer a fee-based lens mount conversion service for its Global Vision lenses. As the name implies, the company will change out the current mount for a mount of your choice, as long as Sigma makes that particular lens for the mount requested. DSLR mounts include Canon, Nikon, Pentax, Sigma and Sony. But Sigma hasn’t forgotten about the mirrorless interchangeable lens camera users among us, who can have their lenses converted to Micro Four Thirds or Sony E-mounts (again, as long as the requested lenses are currently available with those mounts).

When you consider how much photographers invest in lenses, Sigma’s pricing seems reasonable enough. Conversions will cost between $80 and $250, depending on the focal length, plus shipping. Sigma estimates the conversion will take about 4 weeks, which isn’t bad considering the lenses have to be sent to Sigma US in New York and then make their way to Sigma’s factory in Aizu, Japan. At the factory, the lenses will be “updated, calibrated and optimized for the new camera system.” The mount conversion includes a six month warranty, which covers the functions related to the mount updates; this is regardless of the age of the lens. However, teleconverters, USB docks and other accessories are not included under that warranty.

Separate from the lens conversion, the company also just announced that all Sigma products—cameras, lenses and flashes—purchased on or after July 1, 2013 will now benefit from a 4-year warranty. Neither the lens conversion warranty or the 4-year warranty will void each other.
