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.

We apologize for the inconvenience this may cause.
