Mount Conversion Service

Sigma will convert the current mount of your Sigma Global Vision lens to another of your choice. Sigma lenses currently from the Contemporary, Art or Sports line, in Sigma, Canon, Nikon, Sony, Pentax mounts can be converted to Sigma, Canon, Nikon, Sony or Pentax*. Mirorrless lenses can be converted to Micro Four Thirds and Sony-E Mount. They cannot be converted to either an APS-C or a Full Frame format.

As of August, 2013, all Sigma Global Vision are eligible for this service. 

*Subject to mount, parts and service availability. Not all products are available in Pentax and/or Sony Mounts. Please check the specific product page to check availability in those mounts.

The conversion service will be handled by Sigma in Japan so upon receipt, your lens will be sent to Japan to be converted to the desired mount and returned to Sigma America, who will, in turn, ship it directly to you. The anticipated turn-around time for this service is two - four weeks.

The pricing range for this service can be between $80 to $250. 

Shipping and Handling can cost between $25 to $100. 

This service is handled only by the original purchaser of lens. If your lens was purchased in the U.S.A., the Mount Conversion Service will be handled by Sigma America only. Other Authorized Sigma Service Centers will not handle this operation. Please send your lens(es) only to Sigma Corporation America by filling out the Online Mount Conversion Service Request Form and sending the product to:

15 Sigma Corporation of America
Fleetwood Court
Ronkonkoma, NY 11779

Product Warranty
Beginning July 1, 2013, all brand new Sigma Products purchased from authorized Sigma dealers are covered under the 1 year America warranty (North and South America) and U.S.A. extended warranties for a period of four (4) years against defects in manufacturing and workmanship only. Your warranty period begins the day you purchase your Sigma camera, lens and/or flash and runs for a period of four years total from that date. (Please refer to the warranty policy included with your product or see the warranty registration page for each Sigma Product). Please note that the Sigma warranty is valid only to the original purchaser and is not transferable. Grey market products will not qualify for the Sigma warranty coverage.

When sending your Sigma product in for warranty service, please be sure to include the warranty card as well a copy of the original sales receipt as proof of purchase date (the start date of your warranty). Anything deemed beyond normal use will void any and all warranties.   As always, our goal is to serve and support our customers.  Products purchased prior to July 1, 2013 are subject to the previous warranty policy listed below. 

Sigma offers a 90 day warranty for factory refurbished products.

Service Policies

Product Warranty
All brand new Sigma Products are warrantied for defects in manufacturing and workmanship only. Your warranty period begins the day you purchase your Sigma Product and runs for a specific time period depending on the item. (Please refer to the warranty card included with your product or see the warranty registration page for each Sigma Product). When sending your Sigma product in for warranty service, please be sure to include a copy of the original sales receipt as proof of purchase date (the start date of your warranty). Anything deemed beyond normal use will void any and all warranties. As always, our goal is to serve and support our customers.

Gray Market
As of July 1 2012 Sigma no longer has worldwide warranties and any product that is not imported by the Sigma Corporation of America or purchased from an unauthorized  Sigma USA Dealer will not be serviced under warranty regardless of the service required. The Sigma Corporation of America Service department will service these products but it will be at the owner's expense.

Courtesy Updating
In today's day and age of ever changing technology Sigma will, at our discretion, offer some updates if available to the original purchaser of the equipment at no charge. These updates are done as a courtesy and are not considered warranty repairs. Remember, your Sigma Product works correctly with the equipment you owned when you purchased it and is not Defective!

Impact Damage
We do our best to repair Sigma products that have sustained damage due to impact, liquid, or other forces outside of normal use, but there is no guarantee that your item will function exactly as it did prior to damage. All service is performed using the most exacting methods, but sustained damage to equipment may prohibit return to the original condition.

AF Data Adjustment
Due to extreme sensitivity of the digital camera mirror box, more than 5 times as sensitive as that of a film camera, it may be necessary to adjust the AF data in your Sigma lens. At Sigma, we adjust all of our lenses to a neutral focus point during manufacturing. It may be necessary to have your Sigma lens adjusted to your own personal camera. This is a known problem with digital cameras and many companies have included Micro Focus Adjustment capabilities on their high end cameras to address this problem with their lenses. If you are able to do this with your camera and lens combination, there's no need to send your equipment in for adjustment.
