Service Policies

1. Product Warranty

All 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 you purchase and the country in which it was purchased (Please refer to warranty card included with your product or see the warranty registration page for the warranty period 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 this is the only proof of actual purchase date and it is the date when your warranty begins.  Anything deemed beyond normal use will void any and all warranties. As always, our goal is to serve and support our customers as they use our products.  

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.  

3. Impact Damage

Sigma will do their best to repair any Sigma product that has 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 being subjected to said impact, liquid or forces outside of normal use  All service is performed using the most exacting methods but once your piece of equipment has sustained such damage returning it to its original condition may not be possible.

4. AF Data Adjustment
