Headline Features

This is a Maintenance Release which is intended to provide fixes for usability issues in major releases (in this case FoCal 2021). This release addresses the following:

The blog post for the previous release of FoCal 2021 contains details of the big improvements that version brough.

The Release Notes contain the comprehensive list of changes for this maintenance release.

Camera Detection Improvement

Camera Detection is improved in FoCal 2021 MR1

FoCal 2020 included some clever functionality to detect information about cameras before connection, so more information could be shown to you before hitting the Connect button.

However, some reliability issues have come to light in this area, making connection to a camera – especially on macOS – a little hit-and-miss for some users.

We’ve reworked this area of the code to use a far more reliable method which is not only more stable but also much quicker. This should resolve issues people were seeing with long delays while “Detecting Cameras” and other similar symptoms.

One consequence of this change is that until the first time you connect to your cameras after installing FoCal 2021 MR1, the serial number will be shown as a blue question mark in the camera list.

Unknown serial number on first connection
Unknown serial number on the very first connection

Once you have connected for the first time, you should see the serial number shown each time:

After the first connection the serial number is known

Improved Camera Connection

If your camera contains a memory card with a lot of images on, connection to the computer can take some time (seconds to minutes!) and this was triggering issues within FoCal.

We’ve improved the software to give better feedback if this issue is detected – we can’t speed up the connection (it’s down to the operating system – either Windows or macOS), but we have made the instructions clearer rather than just failing to connect in some unhelpful way.

Our recommendation is either have no memory card in the camera when using FoCal, or to have a newly formatted memory card in the camera for tests like Stabilisation Test which require a card.

Better Disconnect Detection

Although it’s an uncommon situation (and one we’d suggest to avoid generally), we try to make FoCal robust if the camera is suddenly disconnected for some reason – e.g. the cable is pulled, the battery exhausted etc.

Just to be clear – it’s much better to hit the Disconnect button in FoCal before removing the cable. But we have made improvements in this area to be more robust against unexpected camera disconnections.

Nikon Fixes

Nikon focus point on LCD

FoCal 2021 brought better detection of the camera focus point setup to catch situations where the camera is not set up correctly, but this has introduced an issue for some users with Nikon cameras when using Calibration Check and other tests that rely on Live View operation.

The symptom is an error message similar to this appearing during tests:

A shot was taken, but no focus points were reported active. You should ensure you are using single point AF mode.

but when the camera is set to single point AF mode.

This issue should now be resolved with FoCal 2021 MR1.

MultiTest Improvements

Reikan FoCal MultiTest lets you analyse across both aperture and focus adjustments to give a 2-dimensional view of your camea and lens performance. It operates in two different modes – one for cameras which support some form of AF Adjustment (e.g. AF Microadjustment, AF Fine-Tune etc), and another mode introduced in FoCal 2021 that is completely hands-free and doesn’t use the camera focus adjustment which allows operation on all supported cameras.

In this second mode, the test works by adjusting the focus position of the lens during the test, but this functionality is difficult to control as different cameras and lenses behave in different ways. The algorithms in FoCal are designed to remove the effects of these differences, but there are some situations where it has been failing to adjust the focus, showing this message:

Failed to adjust focus position

We’ve modified the operation a little in FoCal 2021 MR1 to try a little harder and longer to adjust focus on certain lenses, which should improve the reliability of the test without changing the results in any way.
