Firmware upgrade for Zeiss Touit lenses brings fast hybrid AF compatibility
Introduction
Carls Zeiss lenses just announced firmware 2 for the Zeiss Touit 12mm and 32mm for Sony E-mount. This new firmware update brings compatibility with Sony’s Fast Hybrid AF, an auto-focus system that combines the traditional Contrast detection AF with Phase detection AF. Combining both of these auto focus features adds a greater level of AF precision and improves the response time when tracking AF is used.
This firmware update to Version 2 is also available for the Touit 2.8/50M with E-mount. It corrects apparently noticeable shutter release delays when pressing the release button with activated flash, hunting’ for the focus point with the camera in AF-C mode. All Zeiss Touit 50mm f/2.8 already support phase detection autofocus and the fast hybrid autofocus of newer Sony E-mount cameras with their factory installed firmware.
Update instructions
- Select Menu – Settings – Version on your camera.
- The currently installed firmware version for the camera and lens are displayed.
- No update is required for lens firmware versions (glass version) 02 and higher.
You’ll need to send your lens, carefully packed (in the original box preferably), to a Zeiss service center in your region for firmware upgrading. Zeiss require you to accompany your shipment of the Zeiss Touit with a delivery note you can find here.
