ComponentVersionTypeRelease Date
FoCal – Windows & Mac3.5.3.10600Stable27th June 2022

Headline Features

  • Calibration Check: completely new algorithm allowing operation with mirrorless cameras (e.g. Nikon Z series which support autofocus calibration).
  • Improvements to Wireless Camera Module integration – ability to set country, over-the-air updates, restore a reset unit and queuing of licensing/results when the internet is unavailable.
  • Huge speed improvement to Wireless Module
  • Lots of usability improvements and bug fixes

Known Issues

Note that Raw is not yet supported on the Z9 due to Nikon introducing a new raw compression format. This will be supported as soon as possible.

Windows Installer issue on older versions of Windows

If you are installing on a version of Windows up to Windows 10 September 2018 version, you may encounter an issue where the installer fails to complete.

This is due to internal certificates within Windows having expired – the solution is to run Windows Update on your computer and install all necessary updates. Reboot the machine and the installer should then complete successfully.
