Sigma Issues Advisory for 60-600mm and 70-200mm –Sigma

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.
