Firmware update for SIGMA dp Quattro series to be stopped temporarily

Thank you for purchasing and using our products.

The SIGMA Corporation has released Firmware update ver2.00 for SIGMA dp Quattro series on April 26th, 2017, and found the phenomenon that buttons on the back of the camera may not work when restarting the camera after the update, depending on the camera settings set before the update.

Until the revised version of the firmware become available, download service will be stopped temporarily.

The revised version is planned to be available tomorrow (April 28th), so please do not update the firmware until then.

In case the buttons on the back of the camera work even after the restart, there are no problems with the use of the camera.

For customers using our dp Quattro series cameras, we apologize for the great inconvenience.

We appreciate your continued support for our company and products.
