Sigma product advisory for two lenses

Sigma has issued a product advisory for two lenses, 60-600mm f4.5-6.3 DG OS HSM and 70-200mm f2.8 DG OS HSM, after finding that some copies do not operate or respond to pressing the camera’s shutter button.While only a selection of lenses are affected, Sigma urges Australian photographers who experience the issue to contact local distributor, CR Kennedy, to receive a free firmware update.

Inside Imaging contacted CRK for clarification, but our contact is currently away.

‘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 re-operation,’ the product advisory says.

‘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 apologise for the inconvenience this may cause.’

The applicable products and serial number are:
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

The lens manufacturer says owners cannot perform the firmware update themselves via the USB dock, and a local distributor must be contacted ‘as it requires an adjustment to optimise each lens individually’.

Some lenses within the affected serial numbers have already had the firmware upgrade, which is indicated by a black circle sticker on the lower right corner of the product box.Both lenses were debuted at Photokina 2018, with the 60-600mm going on sale in October 2018 and the 70-200mm in December 2018.
