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]

[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.
