For customers using the SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports and the SIGMA 70-200mm F2.8 DG OS HSM | Sports

Thank you for purchasing and using our products.

With the SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports and the SIGMA 70-200mm F2.8 DG OS HSM | Sports, we have found a phenomenon whereby when pressing the shutter button on the camera body, it may occasionally stop operating and not respond to the reoperation.
In this circumstance, we would like to provide a lens firmware update free of charge to the customers using the applicable products with the serial numbers mentioned below.
We apologize for the inconvenience this may cause.

[Phenomenon]
When pressing the shutter button on the camera body, it may occasionally stop operating and not respond to the reoperation.

[Applicable products and Serial No.]
SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports for SIGMA, CANON EF, NIKON F mount
Serial No.53824160 or earlier

SIGMA 70-200mm F2.8 DG OS HSM | Sports for SIGMA, CANON EF, NIKON F mount
Serial No.53846990 or earlier

[Corresponding method]
For customers using the applicable products with the mentioned serial numbers, we are going to provide a lens firmware update free of charge.
*The SIGMA USB DOCK cannot be used for this firmware update as it requires an adjustment to optimize each lens individually.

[How to identify already supported products]
Among the applicable products with the mentioned serial numbers, those that had their firmware updated have a black sticker on the lower right corner of the product gift box, as shown in the image below.

For further information, please contact your nearest authorized SIGMA subsidiary / distributor.
