Firmware Update

ZEISS Touit 2.8/50M (E-Mount)

A firmware update to Version 02 is now available for the Touit 2.8/50M with E-mount. It corrects the following behaviour that may have occurred with the previous lens firmware version with particular camera menu setting and in particular situations:

• clearly noticeable shutter release delays when pressing the release button with activated flash
• ‘hunting’ for the focus point with the camera in AF-C mode


Important information:

It is not possible to reinstall the previous firmware version after performing the firmware update. Sending the lens to us confirms your acceptance of this.

Important note:

Please make sure that your camera has the latest firmware version installed. Please check with your camera manufacturer that you have the latest version of your camera firmware installed (e.g. website). Please follow the camera manufacturer’s instructions when upgrading the camera firmware.

Checking the firmware version

1.) Select Menu --> Settings --> Version on your camera.

2.) The currently installed versions of the firmware for the camera and lens are displayed.

3.) No update is required for lens firmware versions (lens version) 02 and higher.

Updating the firmware:

Please send your lens to ZEISS for firmware upgrading. It is not possible to perform this update yourself with a firmware download.

Please pack your lens carefully and send it together with a completed copy of our delivery note to the ZEISS Service address nearest to you. Please note that we can only process your order when it is accompanied by a correctly completed delivery note.
