Touit 2.8/12 E-mount & Touit 1.8/32 E-mount:
An update to firmware version 02 is available for the Touit 2.8/12 and Touit 1.8/32 lenses with E-mount. With this version, the lenses also support phase detection autofocus and the fast hybrid autofocus of newer Sony E-mount cameras.
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.
1.) Select Menu --> Settings --> Version on your camera.
2.) The currently installed versions of the firmware for the camera and lens are displayed. If no firmware version is displayed here for the objective lens (this is possible in the case of many camera models) the objective lens is still equipped with an older firmware version.
3.) No update is required for lens firmware versions (lens version) 02 and higher.
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.
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.
