FoCal 2.9 Alpha 3 (with Nikon Z6/Z7 Support)

The third Alpha version of FoCal 2.9 is now available.

This will be a brief explanation of key improvements/differences from the previous version (details of that version here).


Version Number:

Channel: Alpha

Platforms: Windows and Mac


The following is a list of the key differences from the previous version:

  • Added initial support for Nikon Z7 camera. This has been tested extensively but there are still some validation tests to run before final release.
  • Added support for the Nikon Z6 camera. This has been done “blind” – we don’t yet have a Z6 camera in the lab so any feedback on how it works on the Z6 would be appreciated.
  • Fix to connection issue with some Canon/Nikon cameras on Mojave (sometimes seen with lots of images on memory card). The opening of the camera may still be slow if there is a loaded memory card in the camera, in that case recommend testing without a memory card.
  • FoCal Comparison Data is now available in FoCal 2.9 stream
  • Fixed an issue where System ID would change on Windows 10 upgrades
  • Fixed license of new camera failing during opening
  • Various UI fixes
  • Fix to missing images at the end of tests
  • Fix duplicate history entries
  • FoCal Comparison Data is now available in FoCal 2.9 stream
  • Update to internal graphics libraries
  • Update to metadata processor
  • Improvements to handling of low level camera data
  • Better building of report generation tools – should make report production faster
  • Fixes to restore of Nikon settings
  • Speed improvements to overall Nikon operation
  • Dust Analysis test now works
  • Storing of camera settings in more places to ensure proper restore in the event of failure (restores on next startup of FoCal)
  • Fix to bracketing detection and warning on Canon cameras
  • Lots of camera reliability improvements due to use of a new internal automated camera validation tool.
  • Improvements to the Windows installer.

Windows Installation Note

You may experience startup problem if you do not uninstall the previous Alpha version of FoCal (this issue has been fixed but you will need to cleanly uninstall the older Alpha version first).

To cleanly uninstall, open Add/Remove Programs tool, search for FoCal and uninstall all copies that have been installed (may be more than one in some cases).

You should also open Windows Explorer, navigate to:

C:\Program Files (x86)\Reikan Technology\

and ensure the FoCal directory is removed. (You can leave the FoCal 2 directory – this is the current, non Alpha version of FoCal which can happily be installed alongside new FoCal)

Known Issues / Missing Functionality

The following are the main known issues with this release:

  • Semi Auto mode calibration is removed.
  • MultiPoint Focus Test is removed
  • Windows Installer is basic and will be improved
  • No documentation
