Headline Features

  • Fixed an issue which could cause a camera to not connect, raising an error referring to “Type Initializer”. This typically happened when you tried to re-connect a camera which has settings that were unrestored.
  • Fixed an issue where some cameras would fail to connect if you had a lens-cap on or the camera was unable to focus on anything.
  • Fixed an issue where a camera may fail to be recognised by FoCal on a new macOS install, or when it was connected to the computer for the first time.
  • Improved explanation for some error messages
  • Fix to an issue which stopped Target Setup starting after changing a camera.

Known Issues


  • Processing of User Metadata file (meta.json) in file mode does not work on Mac. This is an advanced feature and will be reworked for the next major release.
