Service Policies

Product Warranty
Beginning July 1, 2013, all brand new Sigma Products purchased from a USA authorized Sigma dealers are covered for 4yr USA warranty 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. 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.

Sigma offers a 90 day warranty for factory refurbished products.

Please register your new Sigma product in order to activate your Sigma 4 year warranty.

Gray Market
As of January 1, 2017, 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 for a minimum $250 charge in addition to the required parts and labor charges at the owner's expense. Important Information regarding Gray Market Sigma Products

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. The customer will be responsible for the shipping charges to and from Sigma Corporation of America and/or authorized service centers. 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, it may be necessary to have your 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.
