FoCal 2.9 Beta 3


What’s New?

The big things in this release are:

  • Reliability improvements to Mac camera communications, especially on Mojave
  • Better recognition of lenses on Nikon Z6 and Z7 with FTZ adapter
  • Fix to report correct focal length for longer lenses (e.g. 200-400mm with 1.4x converter)
  • Fix an issue where test would fail for very long exposures during aperture sharpness or dust analysis tests
  • Improved reliability of user interface operations, especially on Mac
  • Improved lens name recognition – thank you to all those sending feedback!
  • Improved internal camera definitions

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


Camera Connections macOS Mojave

Some users reported seeing a problem connecting their cameras to FoCal with macOS Mojave. After a fair bit of work we think we’ve got to the bottom of this issue, it’s all to do with having a memory card with images on in the camera. If you remove the memory card and restart FoCal everything connects as normal.

We’d like FoCal to connect whether there’s a memory card in the camera or not and we’ve now added in specific code that deals with this situation. If you were having issues connecting with Mojave do check out this release and let us know how you get on!


Lens Identification Updates

It’s been great 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 are working on a solution which we’ll add in an upcoming release.


Known Issues

There are a few known issues with this release:

  • There is an issue on some Mac systems which causes FoCal to stop when a report is saved. This only affects a small number of users and we’re having difficulty reproducing this issue, although are adding various fixes around this area. If you experience this problem, please do get in touch with the Feedback button (see below).
  • Semi Auto mode calibration is not present.
  • MultiPoint Focus Test is not present.
  • There is no documentation for this release – please refer to FoCal 2.6 documentation for information.
  • There is an issue with some message boxes not being able to be closed on macOS Sierra and earlier. This does not affect High Sierra (10.13) or Mojave (10.14).
  • With Overlapped Capture & Analysis enabled, failure cases (e.g. incorrect AF Microadjustment set in the camera, target not found etc) are not always handled correctly and may require you to quit the test and restart. If this is a problem, please disable Overlapped Capture & Analysis in the Preferences | Advanced tab.

    Does Fo-Cal come with a target or do I need to buy that separately?

    Looking to calibrate several lenses from 8-15 through to 150-600. What targets will I need?

    Will you dispatch targets to Canada?

    Can I print a target before the purchased ones arrive?

    • Hi Paul,

      Thank you for your interest in FoCal 🙂

      You can print your own targets no problem, check the faq entry How do I print the FoCal Target?

      It’s also possible to purchase pre-printed via the FoCal store (yep no problem to ship to Canada).

      With wider lenses (8mm is very wide!) we tend to suggest to use a slightly larger target so it fills more of the frame (the 210mm target is ideal or print a target that fills an A4 sheet). With longer lenses actually a slightly smaller target works well. If buying a pre-printed target generally the 210mm works well for all cases (with the 150mm working in most all cases except for wider angle lenses)

      Best Regards,

  • I am using a Nikon Z6 and like to calibrate my Nikkor 200-500mm F/5.6 and my Nikkor 70-200mm F/4.

    Is FoCal 2.9 Beta 3 good to use for this combinations?

    Thanks in advance.

    • Hi Daniel,

      Thank you for your interest in the 2.9 release.

      We believe the current 2.9 beta 3 release is very close now to the formal 2.9 release.

      To that end, yes definitely for the Z6 / Z7 give it a go, it should be very much usable and provide excellent calibration results.

      Best Regards,

    Considering purchasing this Software that was suggested by Hudson Henry Photography. There is evidently a series a step below “Pro” that does not address Aperture issues and this is the Series I am interested in.
    What is the math used when determining the distance away from your target with a Telephoto Lens, say 24-120mm F4 VR? Do you set up for mid mm or check the 24 and the 120mm settings.
    Example for 24mm ( 24x50x.0328/12) =3.28′
