Important note
Please make sure that your camera has the latest firmware version installed. If this is not the case, it is possible that the camera may not recognise the firmware upgrade for ZEISS Touit lenses . Please visit the camera manufacturer’s website to check whether the firmware version in your camera is up-to-date and find possible upgrades.
Important information
  • In some cases, the lens may fail to function correctly when an error occurs in the installation of the firmware upgrade. We strongly advise you to read the instructions carefully to avoid such errors.
  • Take care to ensure that the camera contains a fully-charged battery or is connected to a suitable external power source (AC adapter) before installing the firmware upgrade.
  • Leave the battery in the camera, or keep the camera connected to the external power source. Failure to do this could possibly lead to the loss of lens functions.
  • A previous version of the firmware can no longer be reinstated after installation of the firmware upgrade.
Updating the firmware:

1.) Please format a memory card in your camera. This will be required for upgrading the firmware. Please note that formatting deletes all data already present on the card, including protected files.

4.) Please read the licence agreement carefully before you start.
