FoCal 2.9 Beta 2 Now Available

We’ve had loads of great feedback from users of FoCal 2.9 Beta 1 which has been incredibly useful (huge thanks!).  Most users reported big stability and speed improvements over FoCal 2.6 and are getting great results.  There have been some issues reported and we’ve worked to resolve many of these in this new FoCal 2.9 Beta 2 release. FoCal

What’s New?

The big things in this release are:

  • This release is available to FoCal Plus users as well as Pro users (subject to being within active Included Updates Period on 1st October 2018).
  • Fixes to Dark Mode on macOS, and addition of Dark Mode on Windows.
  • Improvements to Aperture Sharpness test
  • Changes to camera control locking
  • Updated Lens Identification

It’s worth reading the sections below for details, and checking out the known issues.  There’s also a detailed changelog available below. There’s also information on how to download this release and give feedback below.


FoCal Plus Support

We didn’t enable FoCal Plus support in the previous Beta version, but we’re very close to the final release and would like to Plus and Pro FoCal users to have access.  If you’ve got a FoCal Plus license and want to give this new Beta a go, please do and send us any feedback using the feedback button as explained below.


Dark Mode Support – including Windows

FoCal 2.9 Beta 1 introduced Dark Mode support on macOS but we got the text and icon colours a bit wrong and some parts were tricky to read!  This has been fixed so it’s much cleaner: We’ve also added the option to use a Dark Mode on Windows.  Open the Preferences > Advanced tab and choose whether you’d like Light or Dark from the Appearance option: When you select Dark and restart, you’ll be using the new Dark theme: Note that on macOS, the selection of Light or Dark mode automatically matches the setting for macOS, so there’s no option within the FoCal application to change appearance – just change it within macOS System Preferences.


Change to Camera Controls Enable/Disable Operation

In FoCal 2.9 Beta 1 we introduced locking of the camera controls when connected to FoCal.  This meant you could not use the controls on the camera to make adjustments unless FoCal explicitly allowed it (or you click the Enable Camera Controls icon at the bottom of the main screen – see below).  We have improved this functionality so the controls are enabled for most of the time, and this fixes some issues where changes you made were ignored or reset when you tried to run a test. You should find adjusting camera settings much easier now.


Aperture Sharpness Test Improvements

We’ve made some tweaks to how the Aperture Sharpness test runs to give you useful information earlier in the test.  Overlapped Capture & Analysis makes the test run faster (especially in Raw mode), but we’ve also added detection for Diffraction Compensation and Vignetting Correction being enabled on cameras which support this as it will degrade the result of the test. Furthermore, we also take shots in a different order to give you the comparison data and wide-open shot earlier in the test run.


Shutter Count Limitations

We often get asked to “re-implement” shutter count functionality, but in reality we didn’t take this away.  This is only an issue with Canon cameras, and it’s to do with Canon’s evolution of how shutter count is reported.

For very early cameras (EOS-1D Mark III era), the DIGIC processor did not report shutter count at all, so we cannot give you the shutter count for these cameras.

After this, the shutter count was reported through the Canon interface software, but around the advent of the EOS 5D Mark III / EOS-1D X Canon made it more difficult to retrieve the shutter count.  We worked around this in FoCal 2.6.5 on Mac and these FoCal 2.9 builds on Windows and can display the value for these cameras.

With the release of the EOS 5D Mark IV and subsequent cameras, Canon totally removed the shutter count reporting by the camera*, so we can no longer report the value for these cameras.

(* technically, we can still read the shutter count but it involves using some totally undocumented commands and poking around in the camera memory – something we are happy to do for our test cameras in the lab but not really happy to release publicly as there is some considerable risk associated with it!)


Lens Identification Updates

It’s been brilliant to receive reports of misidentified lenses from users via the new Report Incorrect link (see below) – thank you to everyone who’s reported lens mis-identification.  We’ve updated our internal tables with the information and you should find they’re recognised correctly now. There are a very small number of lenses that cannot be resolved with information available (due to third-party manufacturers using incorrect values in their lenses).  We have a solution to this which we’ll add in a upcoming release.  


Known Issues

There are a few known issues with this release:

Message Boxes on macOS Sierra and older

There are some situations where message boxes cannot be dismissed on older versions of macOS (10.12 Sierra and earlier).  This does not stop the use of FoCal, it just means you cannot close some message boxes so have to move them out the way and continue using FoCal.  We’re working on a fix for this.

Report Save Crash (Mac)

We’ve had a few reports of FoCal crashing when you tried to save a report, but we have not been able to reproduce this issue on a number of Mac’s and a range of versions of macOS which makes it really difficult to fix!  Some users have sent screenshots which give us a good idea of where the problem is, and we’ve improved some code around this area so hopefully this will resolve the issue.

“No response received from server” issue (Mac)

This message indicates a problem communicating with the camera on Mac.  It’s been a bit difficult to reliably reproduce this issue, although it’s clearly seen with the Canon EOS-1D Mark III camera and we’ve worked to resolve this particular cause.  The communication should be improved but we’re still investigating this to try and find a way to reliably reproduce and fix this issue.

Overlapped Capture and Analysis Issue

There is an issue where if you incorrectly set the AF Microadjustment / Fine Tune value when instructed by FoCal and then set it correctly, you will be asked another time to set it to the correct value (even though you now have).  If you just click OK for this second request, the test will continue without issue.  You may also see a similar issue if a warning is shown during AF Consistency or Aperture Sharpness testing.  We are working on a fix for this issue.

File Mode Limitations

FoCal Pro users should be able to run tests using File Mode on cameras that are not able to be controlled by FoCal (e.g. Sony A7 series cameras), but there is a little more development to be done to get this functionality up to the level of FoCal 2.6.  For now, you may find File Mode operates correctly with other cameras, but we would recommend using FoCal 2.6.x to analyse these if you need to.


Getting this Release

This release is available to all FoCal users (FoCal Plus, Pro and Commercial/Non-Profit) who were within their Included Updates Period as of 1st October 2018. You can get the software in one of two ways:

  • Go to the About > Update Check option in the software, and making sure the Update Channel is set to Alpha or Beta (FoCal 2.9 onwards). From here you can hit the Download button to get the software.
  • By logging in to the LMS at  You should see a “Pre-Release Downloads” section – click this to view the available downloads.

It’s worth just checking the pre-release software FAQ to make sure you know type of software you’re getting.



Beta releases are close to Stable releases of FoCal but will benefit from wider testing with real users. We would love for users to try out this Beta release and let us know what you think!

We’ve added a Send Feedback button in the About panel of the application.  Any bug reports, feature improvement, suggestions and general thoughts are very welcome.

FoCal User Feedback Button

Please do use the Send Feedback button in the software to send information back to us.  This ensures the feedback is sent to the right place and that we have the right information about the release being tested.

We will read all the comments you send us, but please note that for pre-release software these are NOT handled as support requests and we won’t necessarily be able to reply or follow up.

We are going to be pretty active with pre-release updates during this period, so please send feedback and there should be a new version with fixes/improvements along soon.


Thank you!

For those that download, use and provide feedback – thank you very much for your support with FoCal.  This sort of user testing and feedback really is invaluable – it helps us to focus on the things that are important to you, and make sure we deliver high quality software to everyone.

    I just used beta 2 to calibrate a Nikon D7100 with 16-85mm lens. I got an error message saying it was using ISO 64 when the base ISO is 100. I could not change the ISO in preferences as it was greyed out, is this known about or was I missing something?

    • Hi Peter,

      Thank you for trying out the 2.9 beta release and providing feedback.

      It is something we’ve seen raised a couple of times on the beta 2 release and we’ve now got to the bottom of the problem (trick is always trying to work out how to re-produce the issue!).

      The full release of FoCal 2.9 has resolved the problem and will allow ISO to be set 🙂

      Best Regards,

    Dear Madam or Sir,

    I am a user of the Reikan FoCal Pro 2.6.0W software. Following the announcement of the release of FoCal 2.9 Beta 2, I wanted to update/upgrade to this new software version. However, when trying to update via the ‘About > Update Check’ option in the software, I received a message to the effect that my current version of Reikan FoCal Pro 2.6.0W includes the latest updates, without being given the option to update/upgrade to FoCal 2.9 Beta 2. I had the same outcome when I tried to update/upgrade the software by logging in to the LMS site (

    I would appreciate if you could advise me if my current licence for Reikan FoCal Pro 2.6.0W does entitle me to an update/upgrade to FoCal 2.9 Beta 2, or if I need a separate licence for this upgrade/update.

    Thank you very much for your kind help in advance. I am looking forward to your reply.

    Kind regards,

    • Hi Bernd,

      Thank you for your interest in trying out the 2.9 beta release 🙂

      I checked your license and yes you do have access to try out the 2.9 beta release.

      It won’t show up when checking for updates within FoCal 2.6 since it’s a beta release at this stage.

      It will show up in the account system, check the FAQ entry Reikan FoCal Pre-Release Software as it provides more info.

      Best Regards,
