Sigma has announced a product advisory for their Sigma 70-200mm f/2.8 DG OS HSM Sports and Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports lenses. Sigma states that they “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.”
A new firmware update is being offered free of charge, for those with affected lenses, however, it’s not one that you can update yourself. Normally, you’re able to upload new firmware through the dock, but this time you have to send it back to Sigma.
