Replacement Parts and Accessories

Many replacement parts or accessories, such as lens hoods, lens caps, thumb screws or USB Cables, can be found directly on our website or through a local authorized SIGMA Canada dealer. If they are unable to assist, please contact our service department by calling (905)-513-7733 and asking for SIGMA Service or emailing:

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.
