The Release Notes contain a comprehensive list of changes.

Support for the Wireless Camera Control Module

This release of FoCal is the first to include public support for our new Wireless Camera Control Module.

The module is still under development and will be in the hands of our first testers early next year. Places are still open for those interested in helping – check the blog post for more details!

Support for Windows 11 and macOS Monterey

Both Microsoft and Apple have published new releases of their operating systems in the last few months.

Windows 11 brings a clean new look and quite a few new changes under the skin, but is essentially not too different from Windows 10. We’ve tested FoCal on a range of Windows 11 computers and FoCal 3.1 includes some minor improvements to fully support Windows 11.

FoCal is fully supported on macOS Monterey

Apple’s yearly operating system update brings macOS Monterey – macOS 12. Over the years, macOS updates have caused quite a headache for developers, especially for software that communicates with external hardware as FoCal does with cameras. Luckily, this time round everything is working without any issues.

Again, we’ve added some minor updates in FoCal 3.1 which integrate better with macOS 12.

Camera Controls Lock/Unlock Improvements

In order to ensure the camera settings are in a consistent, known state, FoCal locks the camera controls so there is no chance of accidental adjustments. When the controls are locked, the padlock icon on the top right of the FoCal window will be shown in a locked state, and:

  • On Canon cameras, the word “busy” is shown on the top LCD if you try to make any adjustments on the camera,
  • On Nikon cameras, the “PC” text is shown on the top LCD and the controls are not active.

All the time FoCal is in control of the camera, the controls should be locked. Prior to FoCal 3.1, this was not always the case – sometimes the camera was left in an unlocked state which could occasionally lead to inconsistent behaviour. This has now been corrected in FoCal 3.1.

If you need to make any adjustments with the camera connected to FoCal, if you’re not running a test you can click the padlock icon. The controls will be enabled, the padlock icon will shows as unlocked and the message below will be shown:

You can adjust controls on the camera only while the message is on screen. Once you hit the OK button and the messages disappears, the camera controls are locked again.

There will also be times where the controls are automatically enabled for you to make changes as instructed by FoCal – again, this will be indicated by the padlock being unlocked, but also with information messages on screen.

Target Setup Improvements

Before running any tests, it’s a good idea to use Target Setup to make sure that your camera, lens, target and settings are all correct.

Over the 10 years since FoCal was first released, Target Setup has gone through a lot of changes and improvements to make it quicker, easier and more informative. In FoCal 3.1, we’ve improved a few aspects to avoid some usability problems that a few users have reported.

First off, each setting panel now has a small “?” icon on the far right which you can click to jump to the online help for this particular check that’s performed. It gives more details about why the check happens, what to expect and how to correct any issues.

When Target Setup informs you that there are changes to make to various settings, it’s not always obvious you need to stop the test and in some cases unlock the camera controls or disconnect the camera to make those changes.

We’ve added a clear message to show that you must not disconnect the camera without first stopping the test.

If you get notified of issues with a lot of the checks – e.g. Target Placement, Target Distance, Focal Length etc – you can simple make the adjustment on your equipment then hit the Refresh icon to check again and update.

For Camera Settings, however, the test will need to be stopped and the camera controls unlocked. This is now a one-click operation – just hit the Click Here text in the Camera Settings panel if you need to make any adjustments.

Target Setup will stop running, unlock the camera and show the message below. When you’ve made any necessary changes, hit the OK button and the test will resume, rechecking all your settings and showing the results.

Sort options for History

We’ve improved the History page by allowing you to choose a sort order for the camera and lens lists.

Prior to FoCal 3.1, the cameras and lenses were shown in the order in which they first appeared in your results which was not particularly intuitive.

Opening the Settings tab now gives you the option of choosing to sort by:

  • Time
  • Description (alphabetical)
  • Minimum or maximum focal length (for lenses)

Camera Control Improvements

Software to control more than 50 different cameras can get quite complicated, with each camera behaving a little differently to the others!

During use, some of our users discover obscure issues with the control of cameras, or we occasionally find problems during internal testing.

We’ve fixed several obscure issues in this release related to subtler control aspects of both Nikon and Canon cameras, improving reliability and speed of operation during use with FoCal.

Metadata, Camera and Lens recognition Improvements

New cameras and lenses are being released all the time, and we try to keep our detection and description code up to date.

FoCal 3.1 brings new camera definitions for the newly released Nikon Z fc, Nikon Z9, Canon EOS R3 and Sony A7iv cameras – at the moment this improves the results available through File Mode, but when the documentation is available we will add automatic control of the Nikon Z fc, Z9 and EOS R3 to FoCal.

We’ve also improved processing of the image metadata so it works with the new Nikon Z9, fixes some issues with the Nikon Z fc images and also fixed some File Mode issues with Sony cameras.

File Mode chooser updates

File Mode allows you to process images you capture offline and get results for tools like Calibration, Aperture Sharpness and Autofocus Consistency.

Once you have selected a set of files, FoCal will display the list for you to pick the ones you actually want analysed for the chosen test.

If you click the arrow on the far right of each line, it will expand the line to show further details, and for FoCal 3.1 we’ve added the Camera and Lens names and serial numbers where available so you can clearly see the source of the images.

Data Transfer Indication

FoCal 3.1 now shows you when data is being transferred between the camera and the computer with the use of a circular progress indicator on the top-right of the window.

The data transfer indication icon

Usually occupied by the camera controls lock/unlock icon, when data is being transferred between the camera and computer, this icon will show a circle filling to indicate the progress of the transfer to the computer.

The following are supported Operating Systems:

Windows (64-bit)

    I would like to use FoCal to calibrate a couple of 500 mm zoom lenses. How can I upgrade from Pro version to Plus. I tried the link to have on this site, but it didn’t work. Thank you. Gene Neau

  • When will the Nikon Z9 be supported. It’s needed urgently for a F lens to adjust! It’s now nearly 3 month on the market.

  • Vincent Welch Sr. says:

    Can someone from tech support PLEASE contact me? I have filled out and submitted your support form five times over the last two weeks and no one has contacted me. I really would like to resolve my problem.
